Can I suggest how to wake up?
According to what happened to Lufy, you have to have a high level of haki control and power too, did you want to put a minimum of doriki, and secondly be on the verge of death but not die, did you want to stay for a certain amount of time like a minute with a life point with an effect, and when this effect ends the awakening of the fruit is unlocked.
Just as the hakis are awakened with a certain level of doriki, the same thing happens, for example with a doriki level of 6000, when the life is very low, the effect appears and when it ends the fruit awakens, and as long as the doriki is below level 6000 does not happening.
the effect could be called awakening fruit, and if the user is cured, the fruit stops waking up because it is no longer on the brink of death.
