Its not something ive come across but its almost like youre describing hotswapping Operating Systems?

Someone else mentioned this, but your likely best bet is to have virtual machines instead. If you need windows on occasion but use linux as your daily driver, use a VM on the linux host?

If its more for like gaming and such, youll be able to do VMs still but you will likely need an additional GPU - a bogstandard one just for video output for the host, and then the main GPU is “given” to the VM to use
