Have TPM 2.0 and secure boot made a significant difference for CoD in general and Warzone in particular?

I played Warzone off and on for a few years up until TPM 2.0 and secure boot were mandated. My rig is decent but too old to support TPM 2.0, yet I don't want or need to upgrade right now, and the ridiculous seeming prices for SSDs, RAM, etc., make me even more hesitant.

That said, have these measures really made a difference?

I'd rarely encounter cheaters back in the day, and being a filthy casual that was not an important factor as I don't do esports or competitive play.
