As far as I'm aware, there are no governmental regulatory requirements to use AV software. All such requirements are generated by individual organizations, for example this one by NC State: https://policies.ncsu.edu/regulation/reg-08-00-10/ https://policies.ncsu.edu/regulation/reg-08-00-10/ Nobody told NC State to require anti-virus, and the same company that created the requirements isn't going to accept some "minimal" solution to check their own box. Instead they will maintain a list of approved software, and your solution won't be on it.
