    Is there a way to make colliders not physically touch each other but phase through each other yet still detect they overlap each other without using ontrigger events or using trigger colliders?

    You've just described exactly what Colliders set to triggers are for yet you don't want to use them. Could you explain why you don't want to use them?

    I can't use trigger colliders because I am using a non convex mesh collider, which do not work with triggers.

    Sounds like you'll have to use 3D physics queries to test for overlap then i.e. OverlapBox, OverlapSphere or OverlapCapsule.

    Or use a convex collider for a non-convex rendered mesh. Or a composite of convex colliders.
