Select a element only if is not a sibling (immediately or not) of another

Lets have this:

<blockquote>
  <header>header</header>
  <p>no</p>
  <p>no</p>
  <p>no</p>
</blockquote>

<blockquote>
  <p>yes</p>
  <p>yes</p>
  <p>yes</p>
</blockquote>

<blockquote>
  <p>no</p>
  <header>header</header>
  <p>no</p>
  <p>no</p>
</blockquote>

I am searching for a CSS selector (without altering the HTML) that target all the p that are both inside a blockquote but without a header sibling (those with the word “yes”).

I have tried with: blockquote :not(header) ~ p, blockquote > p ~ :not(header), and similar others with no avail. Is this even possible with CSS only?

Unfortunately this is not currently possible in pure css. The first two cases could be covered by overwriting your rules in a sibling selector, eg

blockquote p {
  background-color: hotpink;
}
blockquote header ~ p {
  background-color: transparent;
}

However in the third case while you can match elements based on their prior siblings you cannot select elements based on their prior siblings.

Is there a "previous sibling" selector?

You also cannot select a parent of an element which would allow you to select the children of the parent of a header element.

Is there a CSS parent selector?

Your :not selectors are matching the following:

blockquote :not(header) ~ p = any p with at least one previous sibling that is not a header blockquote > p ~ :not(header) = any element that's not a header element with at least one previous p sibling
