Apply android:tint on XML Selector to a VectorDrawable

Question

My ImageButton have a background defined by a XML selector:

<ImageButton
    android:id="@+id/button1"
    android:layout_width="@dimen/size1"
    android:layout_height="@dimen/size1"
    android:layout_gravity="center"
    android:background="@drawable/selector1"
    android:clickable="true"
    android:onClick="func1">

This selector changes the background image based on the current state of the ImageButton (pressed, focused, "normal") - applying or disabling a "tint" over the source image.

    <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:state_pressed="true">
            <bitmap android:src="@drawable/icon1"
                    android:tintMode="src_atop"
                    android:tint="#40FFFFFF"/>
        </item>
        <item android:drawable="@drawable/icon1" />
    </selector>

These images are either WebP or PNG.

QUESTION: how can I obtain the same behaviour using VectorDrawable (SVG) files? <bitmap> does not allow using a VectorDrawable file as source.

I mean - use only one VectorDrawable for all different states and apply tint/mask to that VectorDrawable to increase brightness or highlight the icon.
