There isnt a specified torque spec for those 3 bolts. You would use the recommended torque spec for the diameter bolt that it isM6. That being said I would tend to do those by feel.

For example if the final torque should be 100 foot-pounds then tighten to 50 foot-pounds first and then repeat the process until youve tightened to 100 foot-pounds. This is called torque-to-yield where you tighten a bolt to a certain point and then it further. This stretches the bolt and helps create a long-lasting clamping force.
