Remove a "main" panel from clientarea

[Alejarne]

Hello everyone,

I am currently customizing the clientarea of my self-hosted install of WHMCS and so far I had no trouble removing entries from the sidebar and other locations. However, I have not been able to find a way to remove one of the four color-coded panels in the main clientarea:

My goal is to specifically remove the "Quotes" panel, which I assumed could be done via https://docs.whmcs.com/9-0/customization/client-area-customization-tutorials/homepage-panels/remove-a-panel/
, but that is apparently not the case since these panels don't have a "menuitemname" tag in HTML like the other elements on the page, so I have no idea what name to put for the hook. I already tried "Quote", but that did not work. 

The reason for why I want this panel gone is that I will not be offering Quotes and therefore have no need for it. If there is a specific setting for this or a different way to do it via a hook, please let me know!
