Even if you upgrade the TPM 1.2 chip to 2.0, the processor your notebook has is still two generations short of meeting Microsoft's minimum W11 processor requirements of an Intel 8th generation core processor or newer and the oldest model series that meets those requirements is the 840 G5.
Whether or not you update the TPM to 2.0, if you are interested in installing W11 on your PC as is, you can read this discussion for how I upgraded several HP and Dell notebook and desktop PC's that did not meet the W11 hardware requirements to W11 22H2/22H3.
You have to use the version of the Rufus utility that I zipped up and attached in the discussion (v3.18).

If the in-place upgrade fails, you should be able to clean install W11 using the bootable W11 installation flash drive you made with Rufus.
