I thought this requires permission to a router. Can you do this say at a dorm or an apartment where internet is provided for you through a portal
You can always configure the DNS manually on a device you own to ignore the DHCP settings sent from the router and just go directly to the pihole, obviously not as good as it happening automatically, but a good workaround if that's not possible
Another user commented that you can run Unbound (the technology used by pihole) on your machine.
Even easier, configure your device to use an ad block DNS resolver. Control D has free ones: https://controld.com/free-dns
