I think it is fine if you install the games on a PC that Doesnt contain any personal data and is only for playing PC games Is never connected to a network, public or private (always offline) Otherwise I wouldn’t recommend ever installing HyperVisor, and if you do, wipe the drive and reinstall the OS. Maybe even better, wipe the drive, destroy it, and then replace it with a new drive. That is the best way to know for certain there is no security compromise on the drive.
