Can I switch HDR and image adjustments together with a Shortcut?

Yes. Create a macOS Shortcut that sets the display's HDR state and then applies your chosen image adjustments. Use explicit On or Off values so running it twice produces the same intended state.

For example, make an HDR viewing Shortcut with BetterDisplay actions in this order:

1. Toggle HDR Mode: choose the target display and On.
2. Toggle Image Adjustments: choose the same display and On to use its configured adjustments.
3. Add Image Adjustment actions for the individual values you want to set. Select the feature and value in each action. The feature must be supported by that display's configured controller.

Make a second SDR viewing Shortcut that sets Toggle HDR Mode to Off and Toggle Image Adjustments to Off, or applies a different set of values if you want adjustments in SDR too. Test both Shortcuts with the display connected and check the resulting HDR state and image.

Toggle Image Adjustments suspends or resumes saved color effects. Their values stay saved. Software brightness remains active, including software dimming and upscaling.

Hardware brightness and contrast also stay unchanged. To change them, add the appropriate Image Adjustment action. The suspension action leaves the global Allow color table control setting and the adjustment method unchanged.

Run these Shortcuts whenever you want to switch SDR/HDR and adjustments together. They apply their actions only when you run them. HDR changes made elsewhere will not trigger the Shortcut, and its image-adjustment values are not added to Configuration Protection. Available HDR modes and adjustment methods still depend on the display and connection.

See BetterDisplay actions in Shortcuts for action parameters, and Configuration Protection for the settings that BetterDisplay can enforce automatically.
