And again you are mixing the topics.
Some posts before you said, you can't use NFC for GPay of file transfer.
Now you say, that the card is recognized? So it seems that NFC is working - but you have an GPay issue.
A solution for this is already posted here. Did you try it? There a 1000 answers for the GPay issue here in the forum.
To say this very straight: Google checks if your mobile phone is save to prevent you from a thief who might steal your data.
Unlocked bootloader, root and other tools or device which is not certified will stop GPay from working.
Now xiaomi.eu, Magisk hide and other tools are fooling Google and make them think that the app is on a safe device.
Using this is your risk and there is no guarantee that it works. Maybe someday in the near future it will be impossible to fool GPay.
So NFC doesn't care about unlocked bootloader. GPay does.
You should sort out first what your problem is an then ask some questions before confusing everyone.
Or keep stock rom on your device. If you don't know the difference between NFC and GPay it's probably the best solution for you... ;-)
