Maybe I'm wrong but I think you can't, even if you set the ContentFlyout to null, the control generates a new context menu when right tapped.

uno/src/Uno.UI/UI/Xaml/Controls/TextBox/TextBox.skia.cs

Lines 824 to 842 in ee6392f

	protected override void OnRightTapped(RightTappedRoutedEventArgs e)
	{
	base.OnRightTapped(e);
	e.Handled = true;
	if (_isSkiaTextBox)
	{
	if (_contextMenu is null)
	{
	_contextMenu = new MenuFlyout();
	_contextMenu.Opened += (_, _) => UpdateDisplaySelection();
	_flyoutItems.Add(ContextMenuItem.Cut, new MenuFlyoutItem { Text = ResourceAccessor.GetLocalizedStringResource("TEXT_CONTEXT_MENU_CUT"), Command = new StandardUICommand(StandardUICommandKind.Cut) { Command = new TextBoxCommand(CutSelectionToClipboard) } });
	_flyoutItems.Add(ContextMenuItem.Copy, new MenuFlyoutItem { Text = ResourceAccessor.GetLocalizedStringResource("TEXT_CONTEXT_MENU_COPY"), Command = new StandardUICommand(StandardUICommandKind.Copy) { Command = new TextBoxCommand(CopySelectionToClipboard) } });
	_flyoutItems.Add(ContextMenuItem.Paste, new MenuFlyoutItem { Text = ResourceAccessor.GetLocalizedStringResource("TEXT_CONTEXT_MENU_PASTE"), Command = new StandardUICommand(StandardUICommandKind.Paste) { Command = new TextBoxCommand(PasteFromClipboard) } });
	_flyoutItems.Add(ContextMenuItem.Undo, new MenuFlyoutItem { Text = ResourceAccessor.GetLocalizedStringResource("TEXT_CONTEXT_MENU_UNDO"), Command = new StandardUICommand(StandardUICommandKind.Undo) { Command = new TextBoxCommand(Undo) } });
	_flyoutItems.Add(ContextMenuItem.Redo, new MenuFlyoutItem { Text = ResourceAccessor.GetLocalizedStringResource("TEXT_CONTEXT_MENU_REDO"), Command = new StandardUICommand(StandardUICommandKind.Redo) { Command = new TextBoxCommand(Redo) } });
	_flyoutItems.Add(ContextMenuItem.SelectAll, new MenuFlyoutItem { Text = ResourceAccessor.GetLocalizedStringResource("TEXT_CONTEXT_MENU_SELECT_ALL"), Command = new StandardUICommand(StandardUICommandKind.SelectAll) { Command = new TextBoxCommand(SelectAll) } });
	}

@ramezgerges would you know if this is possible on Windows?

There seems to be a ContextMenuOpening event that can be Handled to prevent the context menu from opening, but it's currently not implemented in Uno.
