Generally chipset is what limits the scale (e.g. trident2 is 128k ipv4 lpm https://docs.cumulusnetworks.com/cumulus-linux/Layer-3/Routing/ ). If you disable "zebra" daemon, FRR works only in control-plane then you would most likely have a limitation with memory/RAM only. (speed is another issue).
To avoid disabling Zebra daemon, you can use "table-map" to choose the routes to send to Zebra: <http://docs.frrouting.org/en/latest/bgp.html#clicmd-table-mapROUTE-MAP-NAME> For example: route-map DENY_ALL deny 10 router bgp 65000 vrf private address-family ipv4 unicast table-map DENY_ALL exit-address-family -- Avoid unnecessary branches. - The Elements of Programming Style (Kernighan & Plauger)
