TPM operation is a bit confusing. It’s more like a button (where selecting something performs an action) rather than a configuration setting.
You can think of it more like, “what will be done to the TPM when I hit save?” Things like “reset it” or “disable SHA1”. You don’t need to perform these actions unless you are having a specific issue with the TPM.
sneaky
There are some technical terms in the operation menu, but I wouldn’t call them sneaky. What are you referring to?
EDIT: oh, you said “snaky”. Sorry!
