I’d be careful optimizing around “not tripping reviews,” because that wording can get you into sketchy territory fast. For client accounts at that spend, I’d rather use boring corporate cards with proper billing profiles and enough limit than keep cycling virtual cards that Google already treats as suspicious.
Also worth checking whether the issue is really the BIN or if there are mismatches in billing country, business info, account ownership, charge patterns, or failed authorization history. Payments problems can look random, but sometimes the pattern is coming from messy account setup rather than the card itself.
