Yes, it is possible and pretty common to use a manual switch for glow plug control. The most common way that I've seen is using a Ford starter solenoid or other continuous duty high amp solenoid.

Do not use that diagram.
That is for the old style system, 1986 and earlier.
Looked like this in the truck.
You have a new style system, the relay/controller looks like this.
To convert the new style system.
Remove the white wire.
Attach a small AWG wire to that terminal and route it into the interior.
Mount a momentary switch in a conveinent location and attach the wire to one terminal on the switch.
Attach a wire to the other terminal of the switch and run it to a good electrical ground.
Do use a test light to check the ground, there is a lot of metal under the dash that is not grounded.
Your wiring is complete.
To operate,
Turn the key to ON.
Push the switch for 10 seconds.
Start the engine.
