@Mo46625773559580 welcome to the forum.
You did not include your list of plugins in your support request but I do not believe that this feature is a part of Joplin. It seems to be a plugin that was mentioned on this forum but does not appear to be listed on the Joplin Plugin site.
Anyway I have just done a quick test and it seems that after this plugin is installed there are then two commands that use CTRL + SHIFT + V.
I changed the Edge Link MD keyboard shortcut to CTRL + SHIFT + E using the plugin settings (and re-started Joplin) and it worked (at least it did during my very brief testing).
