Xmlrpc file & xfn

Could you please tell me how I can remove xmlrpc file and xfn from my WordPress website and whether they affect SEO. You can find my website in Georgian here.

Here is the code:

<html lang="ka-GE" prefix="og: https://ogp.me/ns#">
	<meta charset="UTF-8" />
	<meta name="viewport" content="width=device-width, initial-scale=1" />
	<link rel="profile" href="http://gmpg.org/xfn/11" />
	<link rel="pingback" href="https://polux.ge/xmlrpc.php" />
