Check in your advanced settings! Every motherboard has its own location for it, but here's a rough idea of where to look for each major brand:
GIGABYTE TPM BIOS Location: Advanced Mode > Settings > Misc > Intel PTT or AMD fTPM > Boot > Secure Boot > Enabled > CSM Support > Disable > Save > Restart
Dell TPM BIOS Location: Security > TPM 2.0 Security OR PTT Security > TPM On OR PTT On > Save > Restart
ASRock TPM BIOS Location:
MSI TPM BIOS Location: Security > Trusted Computing > Security Device Support > Enable
Or: Choose AMD fTPM or Intel Platform Trust Technology
ASUS TPM BIOS Location: Advanced > PCH-FW Configuration/AMD fTPM configuration > PTT or fTPM
