Even if you need more IPs than the 10/8 network provides, there are other prefixes you can use, as long as your hosts do not need to ever directly connect to them, so you effectively have billions of private ips at your service.

Pro-tip: never do this outside of ranges explicitly reserved for private use. Multiple times a year I have to deal with some hospital somewhere saying "well <xyz> didn't use to come from that range!" and then dealing with the fact 10,000 medical devices can't have their IPs changed. Recently a similar thing happened with 1.1.1.1 and 1.0.0.1 when Cloudflare went live with them, nobody ever thought those IPs would be handed out.
