currency switcher position

Editing the place where the currency switcher is displayed can be done if you hide the currency switcher on the product template and add a custom one using shortcode or PHP code in your template, on the place that you desire to be placed.
You can refer to this documentation about the process: https://wpml.org/documentation/related-projects/woocommerce-multilingual/multi-currency-support-woocommerce/#adding-a-currency-switcher-to-the-front-end

It is also possible to design entirely custom switcher and template for it – https://wpml.org/documentation/related-projects/woocommerce-multilingual/designing-custom-currency-switchers-using-template-files/
