Framerate independent Process

Can this be considered a simple yet effective framerate independent method ?

void Update()
{

    if (Time.deltaTime < SPECIFIC_AMOUNT_OF_FIXED_TIME) return;

}

no.

This code will only make that whatever comes after this check in your Update will never be run for people with a fast computer. Time.deltaTime will then always be smaller than this value and thus nothing will ever happen. On the other hand for people with a slower computer this will do nothing.

perhaps if you tried to explain what kind of problem you try to solve with this we might help you find the correct solution.
