Two steps for me:-
A kite in 2 originating from BOX 4 sets r8c5<>2 leading to
An XY-Wing (25) (59) (29) pivoted in r8c5 setting r7c9<>2 solves it.

What about an XY-Wing 792, pivoted in r9c8? I didn't test to make sure, but it looked like all that was needed.

A Skyscraper on 2 in c 24 also looked like a one-stepper, but again, I didn't check to make sure.

Yes, the 279 xy-wing pivot at r9c8 setting r8c2<>2 plays out to a solution.

On a more boring level a UR on 26s in columns 5 and 7 setting R5 C7 to 6
is all that's needed

Code:

+-----------+------------+----------+
| 2  1  3   | 7   8    5 | 4  69 69 |
| 57 57 6   | 4   3    9 | 1  2  8  |
| 4  9  8   | 6   1    2 | 7  3  5  |
+-----------+------------+----------+
| 57 6  25  | 8   27   3 | 9  1  4  |
| 8  27 4   | 279 2679 1 | 26 5  3  |
| 1  3  9   | 5   26   4 | 26 8  7  |
