You can DRS (https://www.dtcc.com/asset-services/securities-processing/direct-registration-system https://www.dtcc.com/asset-services/securities-processing/di...) your shares so that no one can lend them out from you. Some brokers have a setting (opt in or opt out) that disallows lending your shares (or that compensate you if they do).
