What to do if I installed the wrong drivers on the video card (OpenSuse Leap 15)?

Question

GRUB

I decided to install drivers on the GTX650, x11-video-nvidiaG02 is suitable for this version, but YaST had GO3, GO4, GO5. I decided to install GO4, after restarting the PC, the KDE splash screen appears and the computer freezes tightly. How can I roll back without losing data on the hard drive? Maybe something in grub can be registered at boot? (OpenSuse Leap 15)
