You'd need to buy and have transferred a /24 (256) or more of "legacy" IPv4 that was allocated by IANA prior to the RIR system for your region. Then you could either convince your provider to route that block on your behalf or get an ASN and BGP peer at your local IX (or even over a tunnel to one). Getting it transferred to you may require setting up a business depending on your RIR.
All in all you could make the above happen for about the price of a lower end new car in the best case.
There are other ways to get non-legacy IPv4 assignments now but those are leased not owned.
