How to hide a 301 redirect in ahrefs?

I found two of my competitors using 301 redirects. Lets say site1.com 301 redirects to site2.com.

If I check site1.com in ahrefs it shows the 301 redirect, however if I check site2.com in ahrefs I can't see the redirects.
I am 10000% sure there is a valid 301 redirect. Semrush can see it.

So how can I hide the 301 redirect from ahrefs?
Blocking the ahrefs bot in robots.txt is not what I am looking for.

I think they are serving some other code to the ahrefs bot but I even switched the user agent to see and I couldn't find anything.

You cannot hide a 301 redirect in Ahrefs. However, you can use Ahrefs to detect and analyze 301 redirects.
