hi! yes - it’s here: OpenTelemetry Integration with Tyk Gateway
Available since Tyk 5.2 - release notes 
Just a word of caution: please wait for the 5.2.1 release coming soon to use in production, as we have found (and fixed) a performance issue linked to the OTel support, see here: Increasing memory usage after 5.2 upgrade - #16 by scelentano
UPDATE: 5.2.1 has been released: Tyk Gateway 5.2 Release Notes
Let us know what you think!
