Dell N3048 and S5232F BIOS Access procedure

Dear Experts,

I am wondering if someone can help with the information and procedure to access DELL Switch BIOS.

If possible please comment on below queries

1. Can we access Dell Switch (S, N, Z series) BIOS menu ?

2.If yes can we secure the BIOS by configuring a "BIOS Login Password (Not the Boot Password)"

Many Thanks,

Alok
