There is no such thing published by Mikrotik.
If you want, you can download NPK and unpack it (Not that hard - all tools were made public by security researches over year ago. If you can't, don't really bother with anything else). Once unpacked, you can go through files and identify the one which you would describe as "bios". (I am not aware of anything like that. Closest file is "firmware" which can be found in /etc folder)

bin bios file is absolutely different , you can't do that , it should be the bios bootable file.

I think your only hope is to read it out from other device. Mikrotik BIOSes can be downloaded as .fwf files and they are also stored in flash as such, but what you probably need is the "bios loader" code that loads these. Flash/NAND can be fully dumped from LEDE/OpenWRT and that can be booted of network, without flashing it into router.
But maybe... just maybe... a full bios can be found in the protected-routerboot-v6.43.7-enable-6.43.dpk package... good luck.

well, the "fwf" file is exactly the firmware which I talked about and which is part of every "bundle" or "system" NPK package.
If OP thinks he needs a "bin", well, thats his choice. I already told him there is no such thing.
