HolyBro Tekko 32 60A ESC shipped with 32.8 fw

Dear @sskaug I've have one HolyBro Tekko 32 60A ESC that shipped with 32.8 firmware, due to issue with RMPM telemetry I need to upgrade at least to 32.9. ideally to 32.10. The firmware 32.8 is unusable with current BF. Could you please send me the instructions to: stop400kv@gmail.com how to do it.
Thank you in advance.
