NVIDIA GeForce GT 735M : Unsupported video driver

Yes, but my response in that post referred to Fermi Refresh. The GT 735M is a Kepler mobile GPU, whose End Of Support was announced by Nvidia itself back in March 2019. And technically, the GT 735M and other Kepler mobile GPUs remain in "Legacy" support until the end of this month, the only drivers that had been released since March 2019 have been merely security patches to a driver which dated from the end of March 2019. Unfortunately, in between the EOL announcement and the time Adobe released Premiere Pro 2020, Nvidia had updated its mainline driver to branch 430, which now no longer supports Kepler mobile GPUs. And Adobe made the adjustment to now require the mainline driver branch that was current at the time of the given major version's release, which meant that driver version 43x.xx is now the minimum driver version required for Premiere Pro 2020 to run properly.

And when 15.x (aka 2021) comes out this Fall, Nvidia might update its driver branch to 450 or 460, which may become the first driver branch to delete all remaining (read: desktop) Kepler GPU support, and possibly mobile first-generation Maxwell GPU support.
