Do you have an address to burn NFTs?

Yes, there are two burn addresses:

EQD__________________________________________0vo

EQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAM9c

Send an NFT to one of them and you lose access to it permanently. There is no way to undo this, so check the address and the item before you sign.

Note that this isn’t a “burn” in the sense used on some other blockchains: the NFT contract still exists on TON, it just becomes permanently unreachable.

If you only want spam or unwanted items out of sight, you don’t need to burn anything — hide them from your profile instead.
