Nvidia cards in the Maxwell 900 series, 750(ti) can work in MacOS but only with Nvidia Web Drivers. Nvidia stopped at High Seirra and never made any for Mojave or newer MacOS versions. For that card to work you will need to Use the web drivers and either Sierra or High Sierra. Maybe El Capitan?
the only Nvidia cards that work in Catalina “natively” are Kepler 700 series except the 750 and 750 ti models. There are driver packages that can get older cards to work but anything newer than Kepler will not work.
