Anyone?

ANYONE KNOW HOW TO MAKE IT TO WHERE ON MY YT CHANNEL, ONLY CERTAIN CHANNELS I'M SUBSCRIBED TO; SHOW UP IN THE CHANNEL TAB WITHOUT KEEPING THEM ALL PUBLIC OR PRIVATE? I SEE SOME OTHER CHANNELS WHERE LIKE ONE OR TWO CHANELS ARE SHOWN IN THEIR CHANNEL TAB, AND ONE OF THEM I KNOW IRL AND THEY ARE SUBSCRIBED AND THEY ARE SUBBED TO ME AND TONS OF OTHER CHANNELS YET THEY ONLY HAVE THREE SHOWN IN THE CHANNEL TAB
