I want this condition. I added the full code. Please check

@api.model
def fields_view_get(self, view_id=None, view_type='form', toolbar=False, submenu=False):

result = super(Applicant, self).fields_view_get(view_id=view_id, view_type=view_type,
toolbar=toolbar,
submenu=submenu)

# Disabling the edit button for vendor user not in "New" stage
if view_type == 'form':
doc = etree.XML(result['arch'])
user = self.env.user

if self.stage_id.name != 'New' and user.partner_id.is_vendor and user.has_group('recruitment_extension.group_hr_recruitment_vendor'):
# When the user is 'Vendor' and the stage is not 'New' then the edit button will be invisible
for node in doc.xpath("//form"):
# Set the edit to false
node.set('edit', "false")
result['arch'] = etree.tostring(doc)
return result
