There are no colleges in the US that require SAT subject test scores.
Some colleges recommend them (Georgetown, some Ivies), you would need to go to each schools website and/or ask the AOs to verify current information. Some schools will consider the scores if you submit them, again verify on websites.
Some schools that previously required subject tests are now subject test blind (MIT, CalTech, Harvey Mudd).
Strong subject test scores can be additive to your application at the schools where they are recommended or considered, but are highly unlikely to be the difference maker in the admissions decision.
Don’t prioritize subject tests over the regular SAT, and only take them if it makes sense in the context of your applications.
Good luck.
