You'd need to ask a specialist lawyer familiar with the laws for your state, not "Doctor ATOT."
If your employer is happy with your work, asking them to shift you to a different client that is OK with 100% remote work is an option, but we can't tell you whether or not you have any legal right to this.
Even if you do have a right, you might suddenly and mysteriously start getting unsatisfactory performance reviews and then be let go because of them.
