Wont be buying either of them would normally get battlefield but the secure boot is hella annoying for me since not everything on my PC is driver signed for secure boot if there was an easier on off switch inside windows that would allow me to decide when i need it on for such games they would have an easier time of me buying it, got nothing to do with cheating just an annoying option.
If you are on W11 it's automatically enabled. There's no other way to use W11.
If on 10, then I suggest you upgrade drivers if possible. As W10 support nears it's end(coming up very soon), new games will require Secure Boot. No other way around that.
Nope my windows 11 runs with just tpm i have to manually set secure boot in bios to enable that i know this from the bf6 beta tpm is a basic requirement secure boot is not least on the pro version i use which basically everyone does these days tbh
