ignore some headings

Hi
What I mean is if I remove some heading from the table of contents, but they are still there (not shown in the table of contents), will that prevent Google from indexing the titles I hide from the table of contents? Or is google still indexing the title that I hide from the table of contents?

Hi
I don’t mean removing the title, but excluding the title from the table of contents, so the title is there but not included in the table of contents
So the question is, is the title that I hide from the table of contents (not removing the title, just hiding it from the table of contents), can it be indexed by Google?
So is it possible to display the post like the following image: (https://prnt.sc/u7hva2) even though the title is not shown in the table of contents?
Thank you

No, I don’t want to show a heading in the table of contents, but it is displayed in Google search results like the image I submitted above

Hi
I have a post with headings and sub-headings, then I only show the headings in the table of contents, not with sub-heading
Can Google index the sub-headings even though they are not shown in the table of contents?
Thank you

Sorry, I still don’t understand your answer, can you explain again?

Then can I make the post look like the image: https://prnt.sc/u7hva2 (for example, the plugins in the image are not in the table of contents)

Ok, so if a heading is not displayed in the table of contents it will write a no-index script to that heading?
