How i can override Selector="Button:pointerover /template/ ContentPresenter" at runtime?

[GamingCity]

Im setting an template on a AppStyle.axaml for all buttons in the app

	<Style Selector="Button">
			<Setter Property="FontWeight" Value="Bold"/>
			<Setter Property="Background" Value="#343739"/>
			<Setter Property="Foreground" Value="{StaticResource ForegroundColor}"/>
			<Setter Property="BorderThickness" Value="1"/>
			<Setter Property="BorderBrush" Value="#777777"/>
			<Setter Property="FontSize" Value="14" />
			<Setter Property="VerticalContentAlignment" Value="Center"/>
			<Setter Property="HorizontalContentAlignment" Value="Center"/>
		</Style>
		<Style Selector="Button:pointerover /template/ ContentPresenter">
			<Setter Property="Background" Value="#131414"/>
			<Setter Property="BorderBrush" Value="#d7d7d7"/>
			<Setter Property="Foreground" Value="{StaticResource ForegroundColor}"/>
			<Setter Property="Cursor" Value="Hand"/>
		</Style>

		<!--Generic Disabled-->
		<Style Selector="Button:disabled /template/ ContentPresenter">
			<Setter Property="FontWeight" Value="Bold"/>
			<Setter Property="Background" Value="DarkGray"/>
			<Setter Property="Foreground" Value="Gray"/>
			<Setter Property="VerticalContentAlignment" Value="Center"/>
			<Setter Property="HorizontalContentAlignment" Value="Center"/>
			<Setter Property="Cursor" Value="No"/>
		</Style>

		<!--Rounded-->
		<Style Selector="Button.Rounded">
			<Setter Property="CornerRadius" Value="40"/>
		</Style>

But now i have the problem that i want to change the colors based on a manual hex color user input on a specific Button. I can change all regular properties without a problem by code on each button individually, foreground, background, etc. But i have no idea of how to replace the values set here.

	<Style Selector="Button:pointerover /template/ ContentPresenter">
			<Setter Property="Background" Value="#131414"/>
			<Setter Property="BorderBrush" Value="#d7d7d7"/>
			<Setter Property="Foreground" Value="{StaticResource ForegroundColor}"/>
			<Setter Property="Cursor" Value="Hand"/>
		</Style>

Easiest way is to set values via DynamicResource and change this resource

I dont want to change all buttons or all buttons of a class, just individually.
So far my most successfull attempt was a very hacky thing of adding handlers for the PointerEnter and PointerExit to change the value, but not even that works as the default style selector/setter seems to have higher priority.

Controls look for resource from their own resouces or upwards until find one, so you can set them locally to that specific control.
