Had a similar experience with my kobo, but I was able to forward the usb port to a windows 10 virtual machine (using qemu kvm with the help of virt-manager). It might work for you too.
Added bonus: you could snapshot the vm and always have a working copy around.
I've always kept an old Thinkpad around for it, first it had XP, then I upgraded and had Windows 7...my latest laptop has Windows 11 on it.
I had to agree to Windows terms of service, refuse OneDrive and Office365 trial, tracking, windows experience, plus the Microsoft account...such an annoyance when I just want to install some software and use the damn machine like I used to.
