Lubuntu 18.04.5 How install using standard vga driver?

I need to install Lubuntu 18.04.5 32 bits in an notebook with GeForce 6800 GO.
The video card is with problems that only work curreclty if using standard video driver. Perhaps is problems in VRAM. Not problems in others devices or RAM.
If using windows not installing video drivers is possible use the notebook without graphics glitches.
If Lubuntu 18.04.5 32 bits install is started when the nouveau driver is loaded crash the install with video graphics glitches in screen because the video card has problems perhaps is accesing VRAM damaged area.
I believe that if nouveau is disabled have chance of install Lubuntu in my notebook.
How change settings in install to avoid nouveau driver to be loaded and to use standard vga driver ? How also made the same settings in installed Lubuntu ?
Thanks for reply.
