CLI tool like Bitcoin Explorer (bx) for BIP85? multisig?

Looking for a CLI tool like Bitcoin Explorer (bx) that will generate multiple seeds/mnemonics from a single entropy string, as per BIP85

Also one that allows for a decent  multisig scheme? Or if not an automated tool, maybe a recommendation for HowTo docs that are pretty well accepted?

Not worried at this point about transaction signing, but establishing good receiving address and cold storage opsec.

Let me know if these should actually be separate questions, they may just be intertwined in my brain only.
