Hi:
The processor your PC comes with doesn't meet the requirements for W11.
Needs to be an Intel 8th gen core, and yours is only a 3rd gen core.

Rumors are that Microsoft may relax the processor requirements back to the 6th gens after further testing is done, but I highly doubt they will go all the way back to the 3rd gens.
There is no way to install a TPM 2.0 chip in your PC that I know of.
