Could somebody please give me his opinion on the following: Due to some circumstaces I had to store non-kyc with kyc BTC on the same cold storage. Are there risks or can I go on stacking on this advice non-kyc BTC? Living in Europe... advice is really apreciated. Thanks in advance and greets to the community!

Not the best situation. Are they still on separate UTXOs/addresses but under the same xpub? In that case the situation may still be salvageable. If the UTXOs have touched each other (merged or address reused), the former non-KYC coins can pretty much be considered KYC by now.

Thank You for Your help. They are now under the same xpub but on seperated utxos. Was a cold wallet migration and an additional non-kyc amount.

Good to hear!
Addresses cannot be linked back to a common xpub by themselves unless they appear in the same transaction graph.
Be very careful and use a wallet that supports coin/UTXO selection and send only the non-KYC coins to another (new?) wallet. And do your best to NEVER accidentally put KYC coins into the empty address left behind. Wallets should typically avoid reuse AFAIK but you could go extra paranoid and also move the KYC coins to a new wallet and retire the old one to completely avoid that risk.

Don't have experience with Jade, but sounds good to use Sparrow or other coin control-supporting wallet software paired with the Jade to sign the transactions.

Its fine if you have labeled the UTXO'S
Just be extra careful when you spend. Try not to spend more than 1 UTXO at a time & label the change.
That's what I would do anyway

If you're worried about this, the first thing you need to do is to run your own node. If your hardware wallet is querying a third-party node, you have to assume that they have your xPub key and already know all your addresses.
You don't have to trust any third-party nodes when you run your own node. You can verify everything yourself.
Additionally, I would suggest that you use a wallet that gives you manual control of your UTXOs as well as labeling. I personally use Sparrow wallet because I believe it is the most feature-rich wallet in the world.
I actually wrote an article on how to use bitcoin anonymously here: https://www.whatisbitcoin.com/privacy/how-to-use-bitcoin-anonymously
Hope you find something useful in here and am happy to help you with any questions you may have.

Use a different passphrase to avoid having to reveal the existence of non-Skyc bitcoins in a bad scenario.

or go to tradeogre and do the same
