Is there way we can disable default validation done on sp-textfield by adding "valid" and "invalid" attribute?

[bdengada]

<sp-theme theme="spectrum" color="light" scale="medium" style="background-color: var(--spectrum-global-color-gray-100)"> <sp-textfield id="field1" required></sp-textfield> </sp-theme>
In the above example as I have added the required constraint on sp-textfield, on page load I see that spectrum adds an "invalid" attribute to this field and a red border and alert-icon are rendered.
As I want to add my own validation, how I can disable this default validation provided by spectrum?
