is disabling ETAG and Last-Modifed a good option .htaccess

I'm using the below code for caching of files in .htaccess

<IfModule mod_headers.c>
    <filesMatch "\.(ico|jpe?g|png|gif|swf)$">
        Header set Cache-Control "public"
    </filesMatch>
    <filesMatch "\.(css|scss)$">
        Header set Cache-Control "public"
    </filesMatch>
    <filesMatch "\.(js)$">
        Header set Cache-Control "private"
    </filesMatch>
    <filesMatch "\.(x?html?|xml)$">
        Header set Cache-Control "private, must-revalidate"
    </filesMatch>
    #Header unset ETag
    #Header unset Last-Modified
</IfModule>

I'm a bit confused if i should comment the #Header unset ETag and #Header unset Last-Modified or not

below is my default.conf file on apache

CacheQuickHandler off

Etag and Last-Modified have nothing to do with compression, they are cache'ing options. Which is OK to unset anyway because they conflict with Cache-Control, which is a better cache method. So yes, you may disable it.

If you are looking for compression, look into Apache's mod_deflate, mod_gzip or mod_brotli.
