Crimping/clamping brake line instead of bleeding

Gonna be replacing my actuator and brake booster next weekend and trying to fully prepare before I start. I have new OEM parts ready to go. My issue is I might not be able to bleed the system after (not enough jacks + physical limitations on my part).

Has anyone tried clamping the brake line to prevent air bubbles instead of just bleeding it? I saw one video on YouTube where they did it but I can't for the life of me find it again.

Also was told you could "rent" techstream from the dealership but I get bumped around on their phone line then sent to voicemail limbo, every time. Any alternative suggestions for techstream sourcing for a broke (and mostly broken ) amateur?
