Currently, intune supported OS is listed in the following article:
https://video2.skills-academy.com/en-us/mem/intune/fundamentals/supported-devices-browsers#linux
For linux, intune supports:
Ubuntu Desktop 22.04 LTS with a GNOME graphical desktop environment
Ubuntu Desktop 20.04 LTS with a GNOME graphical desktop environment
Currently, I haven't seen that intune manages Remarkable Devices.
Thanks for your understanding.
