If you put black tape over the light, it will not allow you to turn on the camera, however, I believe someone found a hack that said if you started recording and then put black tape over the recording, it would allow you to continue to record, but only for 3 minute increments.

Could you just replace the led with a uv led or a resistor?

If "just" requires ordering specific electronic components and soldering, it's not "just" for most people.

I suppose that really depends on how hard they’re trying to prevent you from doing that…

* They could measure the forward voltage of the LED when driven by a known current. Bonus points for measuring at multiple currents. Remember that the forward voltage depends on color.

* They could measure the reverse leakage current at a known voltage, and compare that to the illumination from the camera’s exposure feedback. Remember that every LED is also a photodiode.

* They could vary the LED driver current to heat it up, then measure that both of the above measurements are compatible with the higher temperature. Remember that most semiconductor properties have a strong temperature dependence.

So it would be pretty easy to detect most simple mods if they really wanted to.

I wonder how that works. How would a LED know if it's covered by tape?

There's light sensor in the same module. The glasses compare light levels between that sensor and the camera, but only at the start of recording.
