I've been using a setup with a GTX 1080 Ti and GTX 750 Ti for a while, where the 1080 Ti is my main gaming GPU and the 750 Ti supports my smaller monitors. Recently, I upgraded to an RTX 5060 Ti for my main graphics card. Since the 750 Ti is no longer officially supported, I had to install its drivers after updating the 5060 Ti drivers released on January 5. However, now with the latest NVIDIA drivers for the 5060 Ti, I can't install the 750 Ti drivers afterward without running into problems—specifically, two ports on my 5060 Ti stop working. I'm currently rolling back to previous drivers and am hoping there's a workaround for using an RTX and a GTX GPU together. Any suggestions?

You might need to roll back to an older driver. Even though the GTX 750 Ti is from the 700 series, it’s categorized as Maxwell architecture, which means it hasn't been compatible with newer updates past the 58x.xx drivers. Try version 581.80 to see if it helps.
It sounds tough! Just so you know, using multiple GeForce GPUs is generally unsupported, but it’s good you've managed a workaround before. Unfortunately, driver compatibility issues can really throw a wrench in the works.
Exactly, and without those updates, playing games like FO76 gets super frustrating. I totally get wanting to keep both cards functioning together!
Have you considered installing another GPU instead? Maybe even going for a third one? Just a thought!
How many monitors are you using? If it’s four or less, you could just connect all of them to the 5060 Ti. The 750 Ti may not even be providing any significant help. If you've got more than four and have integrated graphics in your processor, that could be used too.
I rely on extra monitors for video editing and different tasks. Four just doesn't cut it for my needs!

That’s what I've been doing, but it seems the latest 5060 Ti driver clashing with the 750 Ti drivers is a new issue. It's frustrating!
