How to create navmesh for small scale agents,How to make Navmesh work for super small scales

Since I am working for a mixed reality environment, my game objects and agents have to be of a very very small scale, around 0.01 for most objects. Unity's built in navmesh does not allow me to create agents less than 0.05 in radius and thus I am unable to properly bake a navmesh for my agents. Is there a navmesh package out there that can handle agents of such small size or is there another way I can go about this to make it work? Thanks!
