EOS R5 How to change exposure compensation automatically in Fv mode

Is there any way to adjust exposure compensation automatically without me having to change it?

Often birds come into view suddenly and without warning and I don't have time to fiddle with settings.

Keeping the camera in auto (Scene Intelligent) would work fine, but I need to always have 12 fps drive mode (without having to change it each time I turn on camera) and a high shutter speed for birds in flight (seems shutter lower limit cannot be set in auto).

EDIT: the links I copied and pasted had the language changed from "en" to "ky" during copy and paste.

Fv does shutter speed limit differently than Av as you say. Av with a shutter speed limit and "safety shift" might work better. So far as I can see, "safety shift" is not available in Fv mode, but I might have missed something.

"Auto Range" sets the limits for "Safety Shift": https://cam.start.canon/en/C003/manual/html/UG-03_Shooting-1_0070.html#Shooting-1_0070_2

Other than that, guessing when the bird might be backlit or flying from sunshine to shadow, one must choose between risking clipped highlights or risking noisy shadows and adjust exposure compensation before taking the photo. For brightly colored birds that might move into sunlight, I often set EV -2/3 because in DPP I can brighten the image later by 2/3 or by less if red channel or blue channel clip. If the bird stays in shadow, I have lost a little dynamic range and gained a little noise. The EV -2/3 also changes saturation, so that must also be fixed later.

Adjusting dynamic range can preserve some of the highlights that are not clipped, bu also changes the color curve. https://cam.start.canon/en/S002/manual/html/UG-04_EditImage_0040.html#EditImage_0050_11 "adjusting dynamic range"

What do you mean by exposure compensation?

By its nature compensation is a manual operation, since you are telling the camera to not use its exposure setting, but bias it in some direction. How would you expect the camera to know how to change it, and in what direction?

The exposure setting, of course changes automatically based on conditions in the frame.

Now, this means you might want a different exposure mode, such as spot.
