ssh to a remote terminal and bypassing dotrc files

Question

I want to rapidly execute a remote command using ssh, for example ls -al /path/to/myfile. Unfortunately, I'm using tcsh rather than bash. My .cshrc file is quite long and slow, so I'd like to bypass it. If I were using bash, I could (presumably) run

ssh [email protected] "bash --noprofile --norc" < lsFile

where lsFile contained the ls command. But tcsh doesn't support either of these flags. Is there an alternative way to accomplish the same effect within the tcsh shell?

If not, an alternative would be to condition on something at the top of my .cshrc file and exit it prematurely. I can't simply condition on whether I have an ssh connection, because for most of my ssh connections, I want to run the full .cshrc file. So I'd need to send the conditioning token within this particular ssh command. Is this possible?
