Pdfescape Deskew

I do not know any method to do this by just modifying the pdf. Rotation
by modifying the pdf is restricted to 90°, 180°, 270° AFAIK
The only way to do what you need is to render the pdf to a bitmap,
rotate the bitmap, and write the rotated bitmap to a pdf.
However this could be done in one command (in the command prompt or a
batch file) if you install ImageMagick and GhostScript.
The following command calls ImageMagick's convert which in turn uses
Ghostscript to convert the pdf to bitmap and the bitmap to pdf
(command is here broken into three lines but must be entered in one
command line):
convert -density 300 tilted.pdf -rotate 1.5 -alpha off -monochrome
-units PixelsPerInch -page 2480x3508 -density 300
-compress Group4 corrected.pdf
The options 'density', 'page' and 'monochrome' / 'colorspace' must be
set according to the original pdf and what you want the result to be,
the option 'rotate' defines the rotation angle in degrees (here 1.5 deg
clockwise, use negative number for counter-clockwise), and the option
'compress' must match the image type ('Group4' for monochrome, 'jpeg'
for color).
I had to experiment with the settings to achieve an output pdf with a
file size and resolution comparable to the original. ImageMagick tends
to create output files much larger than the input.
