Is it possible to force Traefik to overwrite an error code with another?

Hello,

I recently found out I was accidentally hosting a unsecured sensitive page online for a couple weeks. I am very concerned that it was scraped. I was thinking of ways of mitigating this, and thought of this - If I could return a 200 code for every page pinged (but still have a 404 page on it), all the real pages would be hidden behind a curtain of useless data.

Thanks
