Please keep in mind that sound technical, administrative, or financial
reasons can exist that hamper one's ability to create RPKI ROAs.

For example, if the IP space is LEGACY, and not covered by a 'LRSA'
(ARIN) or 'Legacy Agreement' (RIPE), then RPKI certificate issuance
services simply are not available for that IP space. Without an
agreement with a RIR to arrange RPKI services, logically, one cannot
create ROAs.

Perhaps in your case, if RPKI is a requirement, you are better off
bringing your own (RPKI capable) IP space?

Kind regards,
