"Is overlapping another object" is useless. These two objects use the "Physics" behavior. The "Physics" behavior can set the collision boundary to a circle. They cannot overlap and can only push each other. The manual shows that offset cannot solve this problem. there is no better way than to detect the distance between the two.
I missed your second post where you mention the Physics, I apologise:
My answer was for non-physical objects.
If both objects have the physics behaviour then indeed the overlaps check will not work, as it will resolve the physics collisions first and push them apart, and by the time it checks for overlaps, it is too late.
1-Distance check is a great alternative.
2-You can also use invisible colliders as an alternative:
Here is one example:
