How to include custom rotation angle within pymapdl legacy function plot_principal_nodal_stress( )

I would like to rotate the default view after plotting stress plot , by 30 Deg ,using the initial cpos returned value stored in cam_pos variable as shown below

using ansys legacy reader

rst = pymapdl_reader.read_binary(result_file)
cam_pos=rst.plot_principal_nodal_stress(
0,
"SEQV",
window_size=[500,500],
background="w",
text_color="k",
add_text=False,
show_edges=False,
#cpos='xy',
return_cpos=True,
show_scalar_bar=True,
lighting=True,
show_axes=True,
off_screen=True,
cmap='turbo',
node_components=None,
element_components=None,
)
is it possible to add the rotation as **kwargs ,like angle=30 or feature_angle=30 ?

other methods which can make this possible are also welcome
