Find Dissimilar Elements in Tuples

Write a Python function `find_dissimilar` that takes two tuples as input and returns a tuple containing the elements that are present in one tuple but not in the other. The result should not include duplicate elements and can be in any order.

#### Function Signature
```python [main.nopy]
def find_dissimilar(tuple1: tuple, tuple2: tuple) -> tuple:
    pass
```

#### Example Usage
```python [main.nopy]
find_dissimilar((3, 4, 5, 6), (5, 7, 4, 10))
# Expected output: (3, 6, 7, 10)

find_dissimilar((1, 2, 3, 4), (7, 2, 3, 9))
# Expected output: (1, 4, 7, 9)

find_dissimilar((21, 11, 25, 26), (26, 34, 21, 36))
# Expected output: (34, 36, 11, 25)
```

#### Constraints
- The input tuples can contain integers.
- The output tuple should not have duplicate elements.
- The order of elements in the output tuple does not matter.
