Hello,
Firstly, sorry to say but according to the Envato Policy, SEO or Site Speed comes under Site Customization and we only provide our dedicated Support related to Theme Options only.
Secondly, regarding the Plugins currently on your Site, following are the ones which are responsible to run your Theme correctly:
WoodMart Core
Elementor
WooCommerce
Other than these all are third party Plugins which you can activate or deactivate according to your needs and requirements. As they are not mandatory at the Theme-level, so it’s your choice in this regard which ones to activate or deactivate. Also, there isn’t any need for Custom Code in this regard. Just deactivate or activate the Plugins under the Dashboard > Plugins.
Hope this helps !
Best Regards
