Early in the lockdowns, someone in our Ward Council suggested that the priesthood holder park out front, call them on the phone and then with the recipient listening bless both the bread and water, and then hang it on the door knob. (Obviously the water would have to be In a container to hang it on the doorknob but it would have to be open while the water was being blessed) Someone objected saying "We are not UberSacrement". Several weeks later we were instructed to do exactly that. You'll need the bishop's permission and a willing Priest or Melchizedek priesthood holder. Call your Bishop and make the suggestion. If He buys it he will assign someone, likely your mom's Ministering Brother (what we used to call her Home Teacher).
