Hello @cnkaragiannopoulos,
Thank you so much for using our theme Corporate Plus. In the premium version, you will get the options to enable/disable link for such area. So we recommend you to check the premium version demo for it.
If you want to do it on free version, you need to customize the theme code. You can find the theme codes on acmethemes/sidebar-widget and check all the available widget and customize as your need.
Note: Child theme is recommended to customize theme.
Regards
