Liquidity sourcing for $HKD options: anyone seeing better?

Finding decent liquidity for $HKD options has been a persistent headache, especially outside of standard expiry cycles. The spreads on anything slightly off-the-run are just punitive. It makes sense given the underlying depth, but I'm curious if anyone has found a regional broker or prop setup that aggregates better flow. Don't want to burn a ton of time opening new accounts for marginal improvement.
