Easy! Just have your subprocess.call pass a special argument, which
you then look for in script2:

subprocess.call(["python", "script2.py","confirm"])

# script2.py
import sys
if "confirm" not in sys.argv:
    print("This script should not be run directly.")
    sys.exit(1)

# rest of script2.py follows
