Wild rabbit nest under garage

Hi
Rabbits have built a nest by burrowing under the concrete slab beneath my garage and I would like to dissuade them from expanding this nest (warren?) and drive them out. I have seen three small, I believe babies, in the hole which is immediately against my garage wall. Unfortunately I think I may have hit one with the weed eater but don't know for sure. That was over a week ago and I have seen no evidence of harm.

The behavior of all 3 seems odd to me, lethargic?, never withdrawing inside when approached but also retreating fully out of sight for long periods sporadically apparently alive and aware.

Any advice how to remove them, they are damaging the lawn around the hole and possibly undermining the garage floor if the warren gets too big. I have no knowledge of rabbits per se nor the extent of damage they might cause but I would like them gone without harming them.

Any advice please?
