Precision T7810 with Turing or Pascal architecture based GPUs

Hello,
I own T7810 currently with Quadro M2000 GPU. I want to upgrade for more powerfull and ideally most recent GPU. I'm thinking about GPU based on Turing architecture. I'm hesitating between GeForce RTX 2080 Ti or Quadro (RTX 4000 or RTX 5000 - these cards are still price available for me, RTX 6000 is too expensive for my budget). I prefer Quadro card because I'm using the workstation not only for rendering but also for various scientific computations. Another card in my mind is Pascal based Quadro P5000.
So, my question is simple - can I use Turing or maybe Pascal based GPU (I prefer Turing) in my T7810, or should I forget on it because of incompatibility or potential problems (in this case solution can be only Maxwell - for example Quadro M6000), please? I understand that no of these GPUs is not listed in the datasheet as supported. There are only Kepler and Maxwell Quadro cards. But other hand I seen that there are selling refurbished T7810 with various Quadro RTX or Pascal GPUs installed. I also found on Youtobe video how to install EVGA GeForce RTX 2080 Ti card into T7810 workstation and tests how it is running. So, it looks that RTX or Pascal is usable in T7810. But I'm rather asking.

I have also one additional question. I learned that in my country are for sale HP or PNY cards, for example HP Quadro RTX 4000. PNY are generally more expensive then HP. Some cards are only available from HP (for example RTX 4000). I don’t found any Dell GPUs.
So my second question is - can i use in T7810 only Dell or PNY cards, or can I also to purchase HP?

Thank You
