Configuring the lock screen on Fairphone 4 using /e/OS 1.8.1

I’m using a Fairphone 4 with /e/OS 1.8.1. I have the lock screen set to accept a PIN code.

When I select a digit, the selected area briefly changes from a circle to a square and lights up. I would like to disable this animation. Is there an option for this?

I suppose you can not disable this without disabling all animations, which is possible in Settings-Accessibility-Text and Display (rough translation from French).

Thank you for the hint.

Unfortunately, even disabling all animations disables only the change from circle to a square. The selected digits still light up.
