Is it possible to only accept incoming connections from full nodes?

Currently running Bitcoin Core 31.1 and in the past I remember a config option to provide search services to light clients (may have been on Knots). Usually about half of my incoming connection peers are breadwallet or bitcoinj clients. Is it possible to only peer with full nodes such as libbitcoin, knots, core, etc?
