Follow up from live chat - Removing W3TC from htaccess

Hi @Ashok

Hope all is well, just following up on our conversation during Livechat on 27th July -

Regarding removing the W3TC Plugin completely from site and htaccess, was checking through the file however there is no direct mention of W3 or W3TC in the htaccess file. only "Expires Caching" section that details out when certain resources cache expire - does this need to be removed? or is that something else?
