Disable shipping charge conversion

Is there a way to disable currency conversion on shipping charges?

I basically have a situation where Gelato’s integration is sending shipping charges using the destinations local currency, which means Curcy is converting it when it shouldn’t be.O

Example, my base currency is AUD, my products are all set in AUD with Curcy converting say to GBP for a UK customer. Shipping is however sent as £5, Curcy thinks it’s $5 and converts it to £2.50.
