Hello,
Unfortunately no.
However, you could write a PHP script that assigns a particular user role to people with such a condition (and removes the user role to people without the condition).
You can run your script and then perform the airdrop to that user role.
To determine user balances via PHP code, use the wallets_api_balance filter:
Hope this helps.
Let me know if you need further advice on how to do this.
with regards
