A number of potential DP patterns but I could not find any that were helpful. I did find this cannibalistic axy-wing step..........
axy-wing(29-3)r3c5+r3c9/r2c6=ls(23)r21c6-(2=9)r9c6-(9=3)r9c3-r7c1=r2c1-(3=2)r2c6-r1c6=r1c7-(2=6)r3c9; r2c8,r3c6<>6
Another interesting pattern is an almost xy-chain:
[(9=3)r9c7-(3=9)r7c1=(9=3)r2c1-(3=6)r2c8-(6=9)r9c8]=(3)r9c8-(3=9)r9c3; r9c456<>9
[Edited one time to add second solution]

I found a couple of wings different only in the number of digits involved.
m-wing (xy) (36)
(3=6)r2c8-r2c6=(6-3)r3c6=(3)r3c3 => r2c13<>3; stte
or
h3-wing (xyz) (326)
(3=2)r1c6-r1c7=(2-6)r3c9=(6)r3c6 => r3c6<>3; stte |

| I used two XY-Wings. The first on 293 pivoted in r9c6 and the second on 692 pivoted in r9c8. Each required a pincer transport to make its elimination. |

| I also used two xy-wings; the one mentioned by Marty in r9c6 and onother one 69 36 39 pivoted in r2c8 with pincer transport 9 from r2c1 to r7c4; r9c456<>9. |
