Are you totally sure your Redmi note 9 has NFC? Some versions don't
Whether or not, you can test it by doing the following (you'll need an NFC tag or NFC equipped bank card etc)
Settings > About Phone > All Specs > tap Kernel Version four times
This opens up CIT
On my phone (model number M2003J15SG) item 31 in CIT is NFC Test
Tap that and follow the instructions
If your phone doesn't register the tag either:
a) your phone doesn't have NFC (likely if this were the case, CIT wouldn't have given you the option to test it though)
b) your tag isn't working
c) your phone's NFC isn't working

For info, I just turned my NFC off and tested that the phone doesn't recognize an NFC tag. Opened CIT and tested it and it recognized the tag - so it seems CIT will test the hardware, even if software is disabling it

If it still won't work, post back with your model number and I'll check if it is supposed to have NFC
