How to Stop WP Feed From Showing Selectively

Hi,

I am the webmaster for the following blog and would like to seek some advice from the pros here.

https://onlinediamondbuyingguide.com/blog/

Can I selectively disable feeds on my blog? I want to prevent people or other sources from abusing and syndicating my content.

www. onlinediamondbuyingguide.com/blog/feed/
www. onlinediamondbuyingguide.com/blog/catergoriesEXAMPLE1234/
=> I would like to disable all these.

The only one that I would like to keep enabled is: https://onlinediamondbuyingguide.com/blog/category/recommendations/feed/

Is there any files or settings I can enable to turn selected rss feeds on or off?

Any advice would be kindly appreciated.

Paul
