How do I keep an increment process continuous without the update function?

Question

  void gravincrease()
     {
         Physics.gravity = grav;
         grav.y -= 0.05f * Time.deltaTime;
     }

I don't want to write this code in update. Because whenever I want, I want to using CancelInvoke. How can I make such a function permanent? or how can I stop these codes for a while when I start a coroutine?

I would just make a WaitForSeconds coroutine with no delay and stop the coroutine through a boolean flag.

 IEnumerator gravincrease(float delay=0f){//default argument - does not need to be filled
          yield return new WaitForSeconds(delay);//wait for delay
          Physics.gravity = grav;
          grav.y -= 0.05f;
          if(!boolFlag)//if your flag is false
                   StartCoroutine(gravincrease(delay));//call this function again
 }

Hoped this helped :). Also as a side note, it is recommended to comment your code and camelcase (or some other method) to name functions and variables.

  bool stopcor=false;
 
  public void gravdown()
     {
         StartCoroutine(downgrav());
     }
     IEnumerator downgrav()
     {
         stopcor = true;
         Vector3 initialGravity = Physics.gravity;
         Physics.gravity = initialGravity * 0.5f;      
         yield return new WaitForSeconds(10f);
         Physics.gravity = initialGravity;
         stopcor = false;
     }
 
  void Update()
     {
         if (stopcor == false)
         {
             if(grav.y>-11)
             grav.y -= 0.05f * Time.deltaTime;
             Physics.gravity = grav;
         }
 }

Thanks a lot for the help. I solved the problem by trying. I also used bool but in a different way.

You can assign a coroutine to a variable like so:

 Coroutine downGravCoroutine = StartCoroutine(downgrav());

You can then stop it later using:

 StopCoroutine(downGravCoroutine());

I guess these codes are so that I can stop the "downgrav" part. The process I want to pause for a while is an increase in gravity over time.
