How to ise custom sni?

My url config:
hy2://user.passs@domain1.com-OR-ip:443/?sni=domain1.com&peer=domain1.com&insecure=0

I want to change the sni to another domain.
hy2://user.passs@domain1.com-OR-ip:443/?sni=DOMAIN2.com&peer=domain1.com&insecure=0

If I just change it, it won't work.

I don't know where to fix the configuration.

Please help me, I want to use a different sni
