I have an HP 27 inches all in one desktop computer 7G9S0AA#ABA, I would like to check if the Realtek RTL8822ce 802.11ac PCIe can be upgraded to AX

Those PC's are not easy to take apart, but if you want to replace the RTL8822CE Wi-Fi card, either of these should work:

Intel Wi-Fi 6 AX200 ax 2×2 + Bluetooth 5.0 MU-MIMO M.2 2230 non-vPro   HP part # / SPS #L35282-005

Intel AX210 Wi-Fi 6E 2x2 AX + Bluetooth 5.2 M.2 2230 non-vPro   HP part # / SPS # M27269-005

I'm not sure that this is the correct service teardown video, but the picture of the PC you have, the shape of the stand matches what this video shows.
