Unfortunately, with stock BIP158, you can't avoid monitoring for reused addresses until you've spent all the coins you want to spend that you previously received to those addresses. That's because BIP158 "basic" filters use the output scriptPubKey to track both receiving bitcoins and spending them.

For example, Alice receives some bitcoins to bc1pfoo in a transaction in a block. The filter for that block commits to OP_0 foo.

Later, Alice spends that transaction output. The filter for that later block also commits to OP_0 foo.

If, in between those two blocks, someone else sent bitcoins to bc1pfoo, then the filter for that block would also commit to OP_0 foo. It wouldn't be possible for Alice's wallet to determine whether the filter made that commitment because new bitcoins were received to bc1pfoo or because of a spend of the bitcoins she had previously received.
