Authorization: To run the tool that removes the password, oh yes I have legitimate access to it, you must enter your Apple Tech username and password into the EFI reset tool. If you enter in the wrong username/password more than four times, the tool bricks the logicboard by blowing the security fuses on the board and in the EFI chip. If they blow, the whole logicboard must be replaced. There is no way around that lockout. No way to reset the EFI password without it.
I also highly doubt you have the needed TPM access device. They're extremely expensive and Apple is very strict about them. Only giving them out to secure locations. It took my work place five months to get one. Had to sign lots of papers and legal documents. Their cool little devices that use Apple private key to access the TPM. That key is not extractable, reversible, or in any way obtainable. Much like the key Apple uses to sigh SHSH blobs for iOS devices. Without that key in the proper TPM device, it won't work. You won't even get to the stage where you enter your Apple Tech username and password.
