Free VPNs to avoid TikTok ban

There’s probably no good solutions to my problem but I’m still curious Is there a free vpn that I can use to avoid the TikTok ban in the US? I’m in high school so I would have to talk to my parents if I were to pay for a vpn, which isn’t something I would like to do. I don’t really know if this would even work considering I have no prior knowledge to vpns. I know free vpns are really sketchy but I would like to know if some are reliable.
