Does anyone know if there's a way to use Steam Remote Play without PIN pairing?

I'm away from home for weeks and only brought my weak ass Macbook Neo, but forgot to pair Steam's remote play before I left.

My desktop at home runs SteamOS and has Wake-on-LAN. So I can power it on, and it shows up my Neo's Steam client, I can hit "Stream" on a game, but then it gives me a pop up telling me to enter the PIN on the host computer (which I cannot retrieve).

How the heck can bypass this requirement? Is it even possible without physical access?

I live alone, my family aren't even in the same town as me. I do have a wireguard VPN to my home, but unfortunately there's no ssh or similar enabled on the system.
