disable comment option

hello, on the page https://www.chefinpasta.net/puntate/ristorante-quin/ i disabled the comment icon and system on the gallery by css but i would like to know if it is possible to disable it from the options panel.

temporary css:
.mainCGdiv .mainCGallery .cgCenterDiv.cg_center_white .cg-center-info-div .cg-center-image-comments-div-parent > .cg-center-image-comments-div-add-comment {
display: none;
}

thank you
