Hey guys! I'm new to Solidity.
I created a BEP20 token and already implemented it on Bscscan, but, I need to block the address of the wallets of the partners and team, which are a total of 13 wallet addresses. With this, we want to generate trust and legitimacy for the project. Doing this by other means is financially expensive at the moment and I would like an explanation of how I can do this.

Thank you for the time.

Is your contract upgradeable?
Are the 13 addresses hardcoded / changeable via any function?
