Can you reach the substrate consciousness through visualization practices

You mentioned that one can enter the substrate consciousness through the shamatha practice of cultivating awareness or during sleep, death and such. Can you realize the substrate consciousness and the luminescence and the radiance of mind through visualization practices such as the one you lead to explore the hearts desire (in motivation to power the retreat talk), through reverence, feelings of gratitude, love, exaltation of breath. I have been listening to your talk remotely now for years and I am so grateful to have this resource to go back to often enough. Thank you.
