fTPM doesn't work

Whenever I boot, tpm_crb can't request region for resource. (mem 0x~~~~) is appeared. So I tried to solve for a week, and I knew that is a firmware bug. It could be fixed by updating UEFI, but there is no update for my laptop, even I didn’t get an update since I bought it…

Then, how can I use fTPM? (it’s sure that tpm already enabled.)
