If your Digital Assets are extremely valuable or sensitive, it is possible to add an additional layer of security by adopting the practice of Hybrid Storage™.
Hybrid Storage™ involves storing part of a Cryptocurrency / NFT (Non-Fungible Token) Encryption Key or Password digitally, and other parts physically (or vice-versa).
Best practice would suggest that the Encryption Key or Password be divided into at least 4 parts for maximum protection.
The advantage gained by using Hybrid Storage™ is that if either the Physical or Digital Safe Custody Vault are breached by criminals ➲ there is not enough information to take control of / or deal with your Digital Asset.
Additionally, when the concept of Hybrid Storage™ is adopted, it is possible for multiple physical backup copies of the partial Encryption Key or Password to be physically stored (even outside of the Physical Safe Custody Vault) without substantially increasing risk.
Each partial Encryption Key or Password by itself is no good without the other parts of the Encryption Key or Password which would be safely stored in other Physical Safe Custody Vault locations as well as in the Digital Safe Custody Vault.
A less effective, but also much more convenient + simpler solution would be to use a Hardware Wallet and store the location of the Hardware Wallet and its access key within the Digital Safe Custody Vault.

The most appropriate additional security solution will depend on your need for convenience / level of risk tolerance.
