How can I reload the payment section in Magento 2 checkout through JavaScript or knockout?

If reloading is not possible, perhaps triggering a reload somehow?

I wish to update the payment section based on minicart changes. Right now I have an ugly solution by reloading the entire checkout page (payment step) again, which forces the payment methods to reload – but I don’t like it, and would prefer an ajax reload.

Anyone got any ideas?

Thanks.
