Customising attributes set in the <form> element

[wilsond-gds]

Hello – currently the hmpo-form macro adds three attributes by default which affect the behaviour of form fields:

autocomplete: "off",
novalidate: "true",
spellcheck: "false"

In some places in our service it would be better to set autocomplete behaviour at <input> level rather than globally on the <form> element. Is there a way of either overriding this macro to customise the behaviour, or a setting within the hmpo-components library that would do this? Thank you!
