I forgot about the cdc site… it states:

Q: Can Shingrix be administered to immunocompromised individuals?

A: While Shingrix is not contraindicated in immunocompromised persons, it is not recommended by ACIP at this time. ACIP will begin reviewing evidence for Shingrix in immunocompromised people as soon as it becomes available and will modify vaccine policy as necessary. You can still give Shingrix to someone who is taking low-dose immunosuppressive medication, anticipating immunosuppression, or has recovered from an immunocompromising illness.
