I can access my RM2 with SSH via WiFi or USB-C, if that's what you mean. But the official reMarkable client is not available for Linux, which I find a bit odd, since it is a Qt-app and the founder of the company apparently is an avid linux user.
I have got it working via Wine, but it keeps breaking after updates. I do not use it often though, as I mostly just upload new files via the website.
