You have a few options as follows
1. 30 hours of flying experience within the last 5 years . Sim hours dont count
OR
2. Pass RTR Part 1 only then apply for renewal
OR
3. Renew your Foreign CPL and Foreign RT and apply for FRESH RTR P instead of applying for renewal
Anyone of the above 3 methods will work
Once you renew it I personally recommend you give both part 1 and part 2 whenever you can and obtain an RTR A with lifetime validity
