Can cloudfare support port 9999

Hello I’m trying to figure out can cloudfare support port 9999 I used spectrum but it only gives me 2 options 1 for domain an the other for ip of website I dont see any option to change port as per the videos I have seen

Spectrum for arbitrary ports is only available for Enterprise customers

Cloudflare does not make exceptions for their supported ports since the IP address is shared between CF customers.
