@KannanCh2 The default HTML/Text caching setting can be disabled by defining the DISABLE_DEFAULT_CACHING variable in global.vars
Define DISABLE_DEFAULT_CACHING

The Surrogate-Control header applies to the Adobe managed CDN. We can use this header and set it based on our requirements

<LocationMatch "^/content/.*\.(html)$">
     Header set Surrogate-Control "max-age=3600"
     Header set Age 0
</LocationMatch>

You might have to check with Adobe on bypassing Adobe CDN. Recommendation might be to point Customer CDN to Adobe-managed CDN.

Many caching rules are taken care of by-default (example assets). The moment we use "DISABLE_DEFAULT_CACHING", we might have more-work at hand to fine-tune the cache.

I would request you to raise an Adobe ticket for clarifications after going through the documentation shared by @Jörg_Hoh

If you are asking if you can get rid of Adobe's CDN, the short answer is NO. This is part of the Architecture of AEMaaCS, you can bring your own CDN and add it on top of Adobe's CDN but it is not really a swap nor a replace.

Hope this helps
