How to automatically apply attribute to all fields in the form when a certain field has a certain value, without having to hardcode domain filters on all fields?

Question

I want to apply the readonly attribute to all fields of the form if a certain condition is met (i.e. when a field has a certain value).
I would be able to achieve this if I hardcoded all the fields in the form with this:-
attrs="{'readonly': [('stage', '=', 'Freeze')]}" But I don't wish to do this. This is not an elegant solution and kind of a brittle implementation.
I would like to have an automatic solution. Is there a built-in method that I can overwrite and apply this readonly attribute for

Hi
You should inherit the fields_view_get method
Try this:

@api.model def fields_view_get(self, view_id=None, view_type='form', toolbar=False, submenu=False):
result = super(SaleOder, self).fields_view_get(view_id, view_type, toolbar=toolbar, submenu=submenu)
doc = etree.XML(result['arch'])
if view_type == 'form':
for node in doc.xpath("//field"):
domain = [['stage', '=', 'Freeze']]
if node.attrib.get('modifiers'):
attr = json.loads(node.attrib.get('modifiers'))
if attr.get('readonly'):
value_r
