<p>I want to maximize security but minimize complexity. Let's say I have large enough sums of BTC that need to be secured into three buckets:</p>

<li>KYC Personal BTC</li>
<li>Non KYC Personal BTC (mined)</li>
<li>KYC Company BTC (maybe uses Lightening/BTC as a merchant for business purposes)</li>
</ol>

<p><a href="https://i.sstatic.net/lgDDC.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/lgDDC.png" alt="enter image description here" /></a></p>

<p><a href="https://i.sstatic.net/GDuTh.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/GDuTh.png" alt="enter image description here" /></a></p>
<p>In this case, I still have the same amount of private keys to manage (nine) but now I also have six hardware devices to manage. Seems to be getting out of hand.</p>

You could give this a little love by replacing the figures for texts.

I want to maximize security but minimize complexity. Let's say I have large enough sums of BTC that need to be secured into three buckets:

1. KYC Personal BTC
2. Non KYC Personal BTC (mined)
3. KYC Company BTC (maybe uses Lightening/BTC as a merchant for business purposes)

I don't want these commingled for privacy, security, but also accounting and taxation purposes. The goal is to have a 2 of 3 multi sig for each category with a hardware signer for two of the private keys with one hot wallet as the third private key. For Example:

Is it possible for each hardware device to have three distinct (seeds) private keys one for each BTC category? In the scenario above I have two hardware devices to manage and nine private keys that need to be physically secured.

If not then my only option us to have a different hardware signer for each private key for each multisig, for example:

Every hardware device that supports HD (hierarchical deterministic) wallets will be able to generate multiple child private keys (and public keys) from a single seed and master private key. Hardware devices generally don't support multiple seeds/mnemonics in parallel. But for what you want to do generating multiple private keys from a single seed is sufficient.
