How to edit Aim property by script?switch to Composer or Hard Look At

See CinemachineVirtualCamera.AddCinemachineComponent() and friends.

However, unless you are making a tool for the editor, it’s better practice to just make multiple vcams with different behaviours and enable/disable them, allowing the CM Brain to make a smooth transition. Otherwise you’re likely to get camera pops.

thanks for you help, problem solved!

How please?

EDIT:
Ok I got it:

            _cinemachine.AddCinemachineComponent<CinemachineGroupComposer>().m_HorizontalDamping = 0.0f;
            _cinemachine.GetCinemachineComponent<CinemachineGroupComposer>().m_VerticalDamping = 0.0f;
