I found the video thought-provoking and it got me looking into the HDR settings in my Nikon D780. I had never used it before and realized it is a good method for making sure that you are getting a good exposure for the shadows. You can set it to take one NEF which has 3 exposures combined (from different shutters speeds when using M) or set it to have all the exposures as separate NEF files. All three exposures are taken almost instantly. If you save the separate exposures you could use LR to combine them. I haven't tried that so I don't know if the results would be different from the composite NEF in the camera.
