Recasting loan with Travis credit union in Bay Area

We are considering recasting our loan (7 year ARM, bought home this Jan at 5.375 rate) as we have received a substantial gift from my husbands family. We are currently with Travis Credit Union in the Bay Area. Has anyone ever recast with TCU? Is this something they allow? I reached out to our mortgage loan officer and he hasn’t gotten back to me yet. Main reason we want to recast is to be able to afford daycare for our twins that are due to be born in the next few months
