Are there any 10G Lan Cards with Map-e like some 10G routers?

I recently got contacted by my ISP, saying I should change to their 10G option, as it saves me money for 6 months. This means changing from 1Gbps to 10Gbps and also my exclusion from the PPPoE service I used to connect to a Ivp4 connection, which is my concern. They use IPv4 over IPv6 (MAP-E) for the 10G plan as an exchange, and I wanted to know if there's an alternative option for a MAP-E router, i.e., a PCIe 10G LAN card that has the MAP-E built in. Or do I need to buy an expensive router for the supposed price drop?

For ref I use Biglobe to connect to NTT. They say a better option is to rent a router, which I'm not interested in.
