Can I delete no cache header in htaccess ?

I added cache header in htaccess myself and untick Browser Cache in WPFC, but there is still a block of

<ifModule mod_headers.c>
FileETag None
Header unset ETag
Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
Header set Pragma "no-cache"
Header set Expires "Mon, 29 Oct 1923 20:30:00 GMT"
</ifModule>

This add a Pragma “no-cache” to each package, I don’t know what’s this? Can I delete this block?
