Provided your inbound flight isn't heavily delayed I wouldn't sweat it – even if you have no fast track + having to do baggage reclaim, counters for TG / VZ / and PG
domestic flights will close T-40 / T-45 / and T-40 respectively, giving you plenty of time to head upstairs to departures level for your BKK - KBV bag drop.
If you have no checked bags and are able to successfully OCI for your BKK - KBV segment, then simply follow signs for Domestic Transfers and head to the lounge of your choice.
