@Solo6R Welcome to the forum!
We’ve been getting a lot of spam on the forum lately, so I had to redact your post in case this was some attempt at marketing to drive traffic to the crypto site that you had mentioned.
However, giving you the benefit of the doubt, you can set the the URI1 field to https://[Redacted].zendesk.com and set the URI2 field to https://www.[Redacted].com (or whatever you have in URI1 currently).
Next, unless you are in the Web Vault, you’ll have to click the 
gear icon to he right of the URI1 field (the Zendesk URL), which will reveal a dropdown menu (in the Web Vault, the dropdown menu is already visible by default, with the label “Match Detection”). Change the dropdown selection to “Never”, and then click the Save button in the upper right corner.
Doing the above should give you a favicon for this vault entry. Unfortunately, the drawback is that the “Launch” button in the Bitwarden apps will no longer work properly for this item (because the “Launch” function always opens the URL stored in URI1).
