Yes there is, depending on what “compliant” means in this context. I expect to be able to use my Openwrt router on any ISP I pay money to.
Your router isn’t a modem, they don’t care what router you use.
Not sure what kind of ISP these guys are, but I’m assuming coax based, in which case they probably are adding terms saying you need to use more modern DOCSIS modems. This is most likely because they are going to start to phase out support for older DOCSIS standards.
