Can a lawyer force their client to communicate in a zoom or phone call even though they have stated they are not comfortable doing so.

A problem has arose with attorney-client relationship. A problem arose with my attorney and their communication with one client and not all clients and the fact that they have overstepped their representation past what was agreed on in the engagement letter. The attorney has threatened that if I can not agree to the terms of meeting and addressing issues through a zoom or call that they will proceed in drafting their termination. I stated that zoom meetings and calls have not been productive, hostile, and not healthy and that I do not feel comfortable, which they then stated that there is no other option. Is this allowed? Can they force me to use a mode of communication despite my wishes and then threaten to terminate? We have used zoom in the past, but I would rather have communication either be text, email, or honestly at this point physical letters.
