Hi @Bryce-huang!

The Gateway API uses different mechanism for setting timeouts.

Did you check this feature https://github.com/projectcontour/contour/releases/tag/v1.28.0

Gateway API: support HTTPRoute request timeouts

Contour now enables end-users to specify request timeouts by setting the [HTTPRouteRule.Timeouts.Request] (https://gateway-api.sigs.k8s.io/reference/spec/#gateway.networking.k8s.io/v1.HTTPRouteTimeouts) parameter. Note that BackendRequest is not yet implemented because without Gateway API support for retries, it's functionally equivalent to Request.
