You can use setCurrencycode($code) method to set your store currency programmatically.

Just Inject following class: Magento/Store/Model/Store

in there a function is defined as:

public function setCurrentCurrencyCode($code)
{
     $code = strtoupper($code);
     if (in_array($code, $this->getAvailableCurrencyCodes())) {
            $this->_getSession()->setCurrencyCode($code);

            $defaultCode = $this->_storeManager->getWebsite()->getDefaultStore()->getDefaultCurrency()->getCode();
            $this->_httpContext->setValue(Context::CONTEXT_CURRENCY, $code, $defaultCode);
      }
        return $this;
  }

Just Call this function anywhere you want and pass the currency code in the parameter.
