Aave swapBorrowRateMode is deprecated

Fixedvaultetfstrategyd2-contracts

TL;DR

Aave_Module exposes aave_swapBorrowRateMode, but the underlying pool.swapBorrowRateMode is deprecated and only available on Aave V2. Calls into the live V3 pool will revert or no-op.

Description

In the Aave_Module there is a call aave_swapBorrowRateMode:

solidity

function aave_swapBorrowRateMode(address asset, uint256 interestRateMode) external
    onlyRole(EXECUTOR_ROLE) nonReentrant {
    pool.swapBorrowRateMode(asset, interestRateMode);
}

The call swapBorrowRateMode is however deprecated; it only exists as a call on the V2 pool.

Consider removing this call.
