Alter the border-radius of dash-to-dock icons

How to alter the border-radius of two dash-to-dock icons when I hover or mouse over them and when some application is open?

Manjaro | Gnome 44

Dash To Dock Settings > Appearance > Customize window counter indicators


And customize the Indicator style border


You will not be able to alter the border around the icons tho, just the background color and opacity, and not all indicators have border.
