Your comment answers itself: it’s nothing inherent to macOS that needs AV scan - it’s the company policy, often driven by external compliance requirements and perhaps a lack of understanding - that leads to the outcome where multiple redundant AV mechanisms end up in your machine.

Multi-AV was bad practice in the late 90's, why are we back here again?

I don't know if the situation has changed but most of them used to tell us to not run multiple ones together.
