Linux Mint 19.3 w 3 monitors and 2 nvidia cards - not working :(

I have 3 monitors (acer b243pwl and 2 acer b243hl) and 2 video cards (nvidia geforce gtx 750 ti)

I’m unable to get Linux Mint to get past a blinking cursor after installing the nvidia drivers 435 through Linux Mint’s software update.

I’ve tried multiple things and reinstalled the OS a few times to start from scratch again but no luck, if I get it to work, it only works on 1 monitor, the moment I try to setup the other 2 monitors, it will no longer go into Linux after a reboot.
