My system (B450M Steel Legend, 3900X) wasn't sleeping right and upon checking the bios found the setting 'Suspend to RAM' (for S3 sleep) 'Disabled'. The only other option was 'Auto', with no 'Enable' available.

I've set it to 'Auto', save the changes and exiting the bios but it's still disabled when returning to the setting.

Is there some other bios option that needs to be enabled for S3 to work right?

I had SMT off.
