How to disable ECN CWR

There is a problem loading the partner’s site.
The partner claims that the reason is the ECN and CWR flags in the packets.
This may not be the case, but it requires that they not exist. How can I achieve this in ROS 7?

Problem solved. The partner on his side found a solution at the link https://serverfault.com/questions/235965/why-would-a-server-not-send-a-syn-ack-packet-in-response-to-a-syn- packet.

But I would like to know if there is an analogue in ROS as in Linux

sysctl -w net.ipv4.tcp_ecn=0

sysctl -w net.ipv4.tcp_ecn_fallback=0
