refactor(evm): Remove unnecessary params "enable_call" and "enable_create"

 - [#1985](https://github.com/NibiruChain/nibiru/pull/1985) - feat(evm)!: Use atto denomination for the wei units in the EVM so that NIBI is "ether" to clients. Only micronibi (unibi) amounts can be transferred. All clients follow the constraint equation, 1 ether == 1 NIBI == 10^6 unibi == 10^18 wei.
 - [#1986](https://github.com/NibiruChain/nibiru/pull/1986) - feat(evm): Combine both account queries into "/eth.evm.v1.Query/EthAccount", accepting both nibi-prefixed Bech32 addresses and Ethereum-type hexadecimal addresses as input.
 - [#1989](https://github.com/NibiruChain/nibiru/pull/1989) - refactor(evm): simplify evm module address
+- [#1997](https://github.com/NibiruChain/nibiru/pull/1997) - refactor(evm): Remove unnecessary params: "enable_call", "enable_create".
