Change Expander Header background without changing the whole style

[steam3d]

Is there simple way to change header background of expander when hovering mouse on it?

Expander has such StaticResource:

 <StaticResource x:Key="ExpanderHeaderBackground" ResourceKey="CardBackgroundFillColorDefaultBrush" />

https://github.com/microsoft/microsoft-ui-xaml/blob/8027ff4af619eb470fab63bf4609c6404ee73e17/dev/Expander/Expander_themeresources.xaml#L14C28-L14C28

I think maybe somehow override it while mouse hovering.

A way can be with PointerEntered/PointerExited
For example, if I change the background of "ToggleButtonGrid" (got from Visual Tree) to Orange :
