Earplugs are definitely allowed. I've had great success in using these for both my Steps and plan on using them for my Step3 as well:

https://www.amazon.com/Macks-Ultra-Soft-Foam-Earplugs/dp/B0051U7W32/ref=sr_1_6?crid=336ZWGVD55IZ3&keywords=ear+plugs&qid=1649609251&sprefix=ear+plugs%2Caps%2C72&sr=8-6

These earplugs (if inserted correctly) along with the over ear headphones that the prometric provides = complete and utter silence.

I used Medical Ethics for the Boards, Third Edition https://www.amazon.com/dp/125964121X/ref=cm_sw_r_cp_api_glt_i_RKG9NDM3C69P1X026A4Y?_encoding=UTF8&psc=1

It was good for step 1 and 2 Haven’t taken step 3 yet
