SFU that does not decrypt or change data in the rtp and rtcp

I am building an application with gstreamer-webrtc in which timestamp in RTCP and RTP is crucial.
while using a mediaserver SFU (mediasoup) the media server consumes and consumes/terminates and produces its own RTCP packets.
Forwarding NTP timestamp from source - #4 by ibc.
I need the original RTCP packets. is there any other SFU that does not consumes/terminates the RTCP and just relay it like a Turn server and SFU combination.
