Can I access Eero router settings through Linux

so we have a Linksys router and a eero router connected to our internet. My stepdad won’t give me the password to the eero and keeps blocking my phone and computer from accessing the router just to be an ass. I’m trying to find a way that I can access our router settings through the command line. Or if there’s a way to change the way my phone and internet show up on router so he can’t keep messing with me ? I have tried a VPN but that didn’t help. I would appreciate any help . Thanks
