I don't have exp with 10k users, but I switched from radicale (which worked great!) to Nextcloud which has cloud functionality in addition to Card/CalDav interfaces too. Perhaps Nextcloud might fit your requirements. https://nextcloud.com/globalscale/
NextCloud's a fine solution. but, the OP's requirements specifically included:
"I also do not want any other other 'crap' just the cal (and card) dav solution."
i suspect it's a more resource-heavy solution than Radicale; but that's an unmeasured WAG. ymmv.
The thing to know about Nextcloud is that it can be thought of as an application container. If you don't want file sharing functionality, disable those bits, etc. You don't have to have all that Nextcloud offers just to have CardDav/CalDav support. Additionally, using Nextcloud for Card/CalDav could give users an alternate webgui to manage their Card/CalDav data. That said, I do agree that Nextcloud for just Card/CalDav alone would be overkill (but it will certainly scale and it's robustly supported)
