Camera Fly/Walk Cross Hair disable feature

The Camera view fly/walk mode (SHIFT+tilda) cross hair cannot be hidden/disabled, as you can with the 3D cursor. Could you consider adding a ‘hide’ / ‘disable’ feature concerning this cross hair please. Here is a screenshot of the cursor I’m refering to: https://i2.paste.pics/6a5c5d94553211845ff6cae5efb9d3ba.png
