EOS R Crop mode selection

I am interested in a unique look of rounded images on a full frame sensor by using APC lenses. I want to be able to turn off crop mode when I mount an APC lens on a full frame camera. Please update the firmware to allow this.

But you can use RF-S lenses on full frame cameras, so not following your logic.

As I understand it, the OP does not want the FF camera to automatically reduce the recording area to that of an APS-C sensor when a RF-S lens is connected - as it does now.   This is done to make the camera produce a non-vignetted image, but the request is to allow that feature to be bypassed for an artistic effect.

Ah, gotcha.  I think it would be a long shot though for Canon to update firmware to allow that.   Do agree with others in doing this work in post.   The resultant images wouldn't of course have the same resolution, but unless very large prints are needed, that shouldn't be an issue.

Actually, if very large prints would be needed (and if the subject is stationary), a single-row or multi-row panorama could be created and then in post, add the vignetting.

If you use a 3rd Party APS-C lens like Sigma or Tamron, on a Full Frame camera, the 1.6 crop has to be manually selected in the menu.  If you leave it in Full Frame, you should see the effect you are looking for.

If you set to 1.6x crop mode, I thought that it should still capture a FF RAW image.  This setting only controls how the RAW image is displayed in post.  

However, ff you are saving as JPG, then the image will be saved fully cropped.

Obviously perform at your own risk, but I just solved this for myself by placing a small amount of scotch tape on the contacts of my crop sensor lens. I was wanting to use the short focal length of one of my old aps-c lenses so just adding the vignette in post wasn't gonna fly for me.
