The inability to enable ESXi secure boot is likely because ESXi is using Trusted Platform Module version 1.2. Secure boot is a feature that ensures only signed, trusted code is loaded during the boot process. For ESXi secure boot to function correctly, the system requires TPM 2.0, which provides the necessary enhanced security features over TPM 1.2. TPM 1.2 does not support these features adequately, which can prevent secure boot from being enabled.
I think this link might add some insite. Talking about how TPM 2.0 is requred. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.security.doc/GUID-10F7022C-DBE1-47A2-BD86-3840C6955057.html
This is a tricky question which can only be answered by way of elimination. TPM 1.2 is a minimum requirement for 6.5 I think whereas 6.7 started supporting TPM 2.0. Since all other answers refer to version 7.0 or UEFI they can't be the reason for potential issues.
