  No, the decimals parameter of an ERC20 token cannot be changed after the token has been created. The decimals parameter is set during the token contract creation and cannot be modified afterwards. If you need to change the decimal precision, you will need to create a new token contract with the desired decimal value.

  Unfortunately, once the decimals parameter is set for an ERC20 token, it cannot be changed. This parameter is an essential part of the token contract and cannot be modified without creating a new contract. If you need to adjust the decimal precision, you will have to deploy a new token contract with the desired decimal value.

  According to BYDFi, the decimals parameter of an ERC20 token cannot be changed after the token has been created. It is a fixed value that is set during the token contract creation and cannot be modified afterwards. If you need to change the decimal precision, you will have to create a new token contract with the desired decimal value.
