You can use double asterisk ** for unpacking the multiple variables to turn to a single object

class Branch(BaseModel):
    name: str
    regionID: str


def check_type(obj):
    return f"{obj}  \n  type: {type(obj)}"

I created this class and type checker, then i created the branch object

branch = Branch(name='jfslkjf', regionID='fdfasd')
check_type(branch)

Out: name='jfslkjf' regionID='fdfasd'  
     type: <class '__main__.Branch'>

Then i converted to a dict

branch_dict = branch.__dict__
check_type(branch_dict)


Out: {'name': 'jfslkjf', 'regionID': 'fdfasd'}  
     type: <class 'dict'>

So on i used double asteriks to unpack it

test_branch = Branch(**branch_dict)
check_type(test_branch)

Out: name='jfslkjf' regionID='fdfasd'  
     type: <class '__main__.Branch'>

You can simply spread the dict back into the Branch.

branchDict = {'name': 'jfslkjf', 'regionId': 'fdfasd' }
branchObj = Branch(**branchDict)
