Nevermind, got it working.
For anyone having the same problem, use
function jptweak_remove_share() {
if ( is_buddypress() ) {
remove_filter( 'the_content', 'sharing_display',19 );
remove_filter( 'the_excerpt', 'sharing_display',19 );
if ( class_exists( 'Jetpack_Likes' ) ) {
remove_filter( 'the_content', array( Jetpack_Likes::init(), 'post_likes' ), 30, 1 );
}
}
}
add_action( 'loop_start', 'jptweak_remove_share' );
