I thought I tried this before and it still showed the menu with its menu grayed
out, but maybe I set it on the submenu item, but I solved my issue by calling
menu.setDisabled(True) on the QMenu. I reset it to False after my editing is
done so the context menu is available again.
If anyone thinks of a better way feel free to answer, but this will work for
now. I was hoping the setContextMenuPolicy methd would work.

Subject: Re: [QGIS-Developer] Temporarily disable map canvas right click
showing Copy Coordinates
I am not using QgsMapTool.
T o capute mouse events, I declared my class as
class AoiSizeValidator(QWidget):
And added
def eventFilter(self, source, event):
with code that captures mouse click events.
I tried using
iface.mapCanvas().setContextMenuPolicy(Qt.NoContextMenu)
and
iface.mapCanvas().setContextMenuPolicy(Qt.PreventContextMenu)
But it did not work. I found that suggestion on a site where someone was
looking to disable the context menu for QWebEngineView, so thought it would
work for the map canvas.
I did find half a solution by setting
iface.mapCanvas().contextMenuAboutToShow.connect(self.disable_context_menu)
def disable_map_canvas_context_menu(self, menu: QMenu, event:
QgsMapMouseEvent):
menu.clear()
which basically completely clears the context menu from all its widgets, but I
would like he menu back after my right click event happens to end the edit
session.

Are you using a custom QgsMapTool subclass? If so, implement the "flags" method
and don't return the ShowContextMenu flag.
