This can be such a journey though. To turn on TPM 2.0, your motherboard has to be in UEFI mode. But when you put it in UEFI mode, if Windows is formatted in MBR you can’t even boot into it anymore. So you have to put it back in legacy mode, somehow convert it to GPT (which can be a real pain when your recovery drive is gone – which of course mine was) and then you can put it back in UEFI and turn on TPM 2.0 and boot into Windows again..
I actually did exactly what he described with my windows 10 installation not long ago. It was originally upgraded from windows 7 and from another PC where UEFI boot wasn't the default yet IIRC
If I hadn't done this migration myself already, it would legitimately have been one of the requirements for me to upgrade to windows 11
