If you have InDesign CC 2019, when you select a Hyperlink and look in the Properties panel, you will see 3 buttons – ‘Remove Hyperlink’, ‘Edit Hyperlink’ and ‘Manage Hyperlink’.
Remove Hyperlink does what it says – it removes the hyperlink. However, it retains the applied Character Style which can be manually changed by clicking the [None] style in the panel.
Manage Hyperlink opens the Hyperlinks panel (if it’s closed) and Edit Hyperlink lets you edit it.
Hope this helps.

I had the same problem. The solutions is pretty simple but a bit tricky to find.
Edit Hyperlink > Character style > Style (from list select "None") > Ok
And thats it. it removes hyperlink.
Hope it helped. :)
