There are indeed some different methods which makes it confusing.
Bottom line: vTPM is not strictly needed, but to have a supported configuration it must have a vTPM.
Also, you can't clone a VM with a vTPM switch, that's why you have the option in Horizon to add a vTPM on the VDIs while provisioning. So, for me, the best way is to have your golden image without vTPM and use the option on the desktop pool to add a vTPM during provisioning.
To setup your golden image initially, you can either choose to do a workaround and install Windows 11 on a VM without vTPM, or you can create a VM with vTPM, install Windows 11 and then remove the vTPM after installation.
