Entering isolation mode is specific to certain isolated assets that are voted on and approved by Aave Governance. You cannot utilize non-isolated assets as collateral to enter isolation mode. The steps to entering isolation mode are as follows:

1. From the dashboard select an isolated asset to supply.
2. You will then see an information notification explaining that you are entering into isolation mode.
3. Once you have successfully entered isolation mode, you will then be able to supply an isolated asset.
4. You can also borrow assets once in isolation mode; however, you will only be able to borrow stablecoins up to a certain debt ceiling.
