Accessibility
The UEFI firmware settings can be entered by pressing F2 repeatedly during boot.
You can access the boot menu with F12.
The "Novo" menu, which allows you to enter the boot menu or the bios setup, can also be accessed by holding Fn while turning on the computer, or by pressing the small "Novo" button underneath the laptop with a small pin (e.g. sim card removal tool).
The interface can be fully navigated and controlled with a keyboard, with the bios setup being also possible to navigate with the mouse or the touch screen.
Firmware
fwupd does not support this device. You can update the BIOS from Windows.
Speakers
Starting with Kernel 6.8 all 4 speakers work.
Microphone
As of Kernel 6.3, the microphone is detected and functions as expected.
Webcam
Webcam is fully functional (albeit not great quality), and the IR camera works without issues with Howdy.
Fingerprint reader
The fingerprint reader on this device is a "Shenzhen Goodix Technology Fingerprint Reader". Goodix does not provide official Linux support for this specific fingerprint reader (or most of their products). There is work in progress to support this with Fprint, however for now it is only unofficial and according to upstream "should be fully functional right now". Check #See also for more information.
Something else to consider is that due to the nature of this specific hardware, having seamless support for dualbooting with Windows is unlikely to be possible, and you have to disable the drivers in Windows if you want to use it in Linux with the unofficial work-in-progress support.
To install the driver for the 06cb:00be, follow the guide on GitHub
To install the driver for the 27c6:55b4, follow Lenovo Yoga 7i#Fingerprint reader.
Tablet Mode
Tablet mode detection is still a maturing part of Linux, and is going through a lot of development changes both in the kernel and user space (e.g. desktop environments).
Currently, your mileage will vary depending on the specific software you use.
The accelerometer in this device is supported, and you can install iio-sensor-proxy to allow use of this by common software like GNOME and KDE.
Check out Tablet PC for more information.
Tablet mode detection seems to work reasonably well with disabling the keyboard and touchpad.
It is supported by the lenovo-ymc kernel driver, so windows managers can switch to tablet mode.
The touchscreen and pen support are functional, though extra buttons on pens such as on the Lenovo E-color Pen are untested.
Keyboard
The internal keyboard is fully functional without any modifications in kernel 5.20 and later.

Suspend
See Power management/Suspend and hibernate#Changing suspend method for the general context.
S3 (Suspend to Ram) is not supported by the UEFI, with seemingly no way to enable it. (Perhaps there is a hidden debug uefi menu? even then it might not be properly implemented).
Issues happening when trying to suspend (for instance with systemctl suspend) include:
- The laptop exiting suspend mode immediately (seems to be solved by upgrading to kernel 6.1 [1])
- The SSD becoming inaccessible until reboot, causing most software to no longer work (seems to be a Samsung drive issue [2], and to be solved in kernel 6.1.46 onward)
It is possible to enable S3 by patching [3] the DSDT, although despite dmesg | grep 'ACPI.*supports S' then showing it to be supported, trying to suspend might still produce the same issues as before.
s2idle support on Ryzen systems is getting better by the day, and approaches like suspend-then-hibernate (check out Power management can help mitigate long term power drain.
