Custom Keyboard Handling in QML: Disabling Default Screen Shift on iOS/Android

I’ve noticed that when the virtual keyboard opens in a QML application on iOS and Android, the screen shifts upward to keep the text input field in view. I’d like to implement my own custom mechanism for handling this, something similar to how KeyboardAvoidingView works in React Native, by adjusting the layout when the keyboard appears.

How to completely disable this default behavior when the keyboard opens?

import QtQuick

Window {
    visible: true
    flags: Qt.MaximizeUsingFullscreenGeometryHint

    MouseArea {
      anchors.fill: parent
      onClicked: forceActiveFocus()
    }

    Rectangle {
        anchors.fill: parent
        color: "#f5f5f5"

        Text {
            anchors {
                top: parent.top
                left: parent.left
                right: parent.right
                bottom: inputBox.top
                margins: 10
            }
            wrapMode: Text.WordWrap
            text: "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

        }

        Rectangle {
            height: 60
            anchors {
                left: parent.left
                right: parent.right
                bottom: parent.bottom
                margins: 10
            }
            color: "white"
            radius: 8
            border.color: "#ddd"

            TextInput {
                anchors {
                    fill: parent
                    margins: 8
                }
                text: "Text input control"
            }
        }

    }
}
