Hello there, this is Emily.
I don't think you can do the Ctrl+Left click to do this, however, you can do the two-finger touch to do right click. Make sure it is set up though: Settings > Bluetooth & Device > Touchpad. Click on Taps to expand that section and make sure the "Tap with two fingers to right click" is checked.
Another alternative is via the keyboard entirely. Most keyboard has the ctrl key on the right that carries the context menu icon. Usually you need to hold down the Fn key and this ctrl key together to do the right click. Or Shift+F10, Shift+Fn+F10 could work too.. Just keep in mind, not all devices use the same keyboard shortcut.
