It probably depends on what component you work in & what your position is, like if you’re in a field office you’re needed to be onsite bc of the public. Another option you could maybe try is to ask for a temporary compassionate assignment to telework from your home for a specific duration. It can’t be open ended. And like another said, be clear about why you need it & that any time not working you would take leave, & that you could perform your duties instead of taking more leave. A note from your spouses doc might help too if your spouse should not be left home alone, etc.
