Testing some behaviors on a collator, I often end-up with [🌗] Block import error: State Database error: Too many sibling blocks inserted
Is there way to remove those siblings from the database ?

As per my understanding, there is nothing that enables you to drop siblings arbitrarily from db atm, though siblings are pruned when ancestor blocks get finalized so ensuring a small finalization window should prevent these.– Alejandro - R 0 G U ECommented Jun 15, 2022 at 14:37

The correct way to revert the siblings is to use ./binary revert ...
Ex: polkadot revert --chain=rococo-local 1
This was not possible for parachain due to how they treat leaves and best blocks (dependant on the relaychain), but has since been fixed (see https://github.com/paritytech/substrate/pull/11716)
