I had asked a question similar to this in the past.
In Atlantic City and Connecticut, you can ask the dealer to reveal the burn card and risk suspicion.
Sometimes they'll reveal the burned card without being suspicious.
However, in a 6-deck game, the contribution of the burned card is so small that it's negligible.
For 6-deck games, ignore the burned card.
If you count it as a 10-value card, you run the risk of not betting enough when you have an edge.
