remove the source link/ permalink RSS feed

This article might help you https://kinsta.com/knowledgebase/wordpress-disable-rss-feed

Thanks, but I didn’t mean the feed link in its entirety
I mean the URLs between the <link> and <guid>
because I only want to display a summary in the rss feeds and not that he automatically creates a read more button by the site url that are in it

<item>
		<title></title>
		<link>i means this url</link>
		
		<dc:creator><![CDATA[]]></dc:creator>
		<pubDate></pubDate>
				<category><![CDATA[Geen categorie]]></category>
		<guid isPermaLink="false">and maybe this one/guid>

					<description></description>

		
		<enclosure url=" />	</item>
