Is there a recommended way to generate descriptor files for the gnoi protos?

[AnandJyrm]

When generating decriptor_set for the gnoi protos, there is an error in handling the imports.

protoc --descriptor_set_out=system_proto.desc -I./gnoi/ -I./protobuf/src gnoi/system/system.proto
github.com/openconfig/gnoi/common/common.proto: File not found.

We can modify the proto and give relative paths instead of the github repo path and it works. Wondering if there is a better way

We want to use this descriptor files with grpcurl/grpcui to access services on our devices.. Is there a recommended way for this?
(reflection service on the server side is currently out of question for us).
