Do you mean "your address" instead of "wallet"?

Use "coin-control" to spend that output specifically, then send it to somewhere or back to the address in the input, spend the other outputs on another transaction as well.
But sending that away will not get rid of its link to the other UTXOs associated with that address,
The heuristics that link addresses or transactions together would still consider that address as one of the recipient of whatever that transaction is for,
All UTXOs associated with that address is obviously considered to be owned by its user (you).

The best solution to that is to simply do not reuse that address anymore and use another address of your wallet.
If your wallet only issue a single Bitcoin address; consider switching to another with better level of privacy.
