Help with using an Internal URL in SharePoint column with out the https:// being present

Hi, any help with this enigma! would be much appreciated. I am using SharePoint 2016 on-prem,,,,,

ISSUE:
I have created a new SharePoint list and would like to use an an internal URL in a SharePoint hyperlink column control. The Internal URL loads a client-side program. Unfortunately, the hyperlink control insists on the https:// to be present. The internal URL does not require http:// or https://.  See image of the internal URL .


I have tried using a new 'single line of text' column and the Edit Source option to add a <a href> tag to create a hyperlink for the internal URL and some javascript. Again, SharePoint strips out the code leaving a dud hyperlink.

Is there a column / setting that allows a URL without the https:// OR is there a way of using the SharePoint hyperlink column initially with the https:// and then (via code) when the hyperlink is clicked on the https:// is ignored / removed and the Internal URL is just read?

Thanks in advance.
