I'm surprised they stopped showing those options in the datasheet. They used to have those in the spec sheet when I bought Edgecore hardware some years ago. Seems like you will have to contact sales teams.
If it can help, I use AS5916-XKS and the TCAM supports millions of routes. Out of my mind, it is something like 6 or 10 millions for IPv4 and 1.5 millions for IPv6.
