Just use the old photographer's trick ...
You pick the background spot on the table -ideally dark or black card / plastic / glass .... or whatever ..
Have a suitably sized box / food mixing bowl ready and place it over the top of your snake ... you can put the bowl / box down and carefully feed the snake underneath .You or someone may have to hold the cover down ...
Leave it be for 5 minutes maybe less but don't take your eyes off the snake / bowl .
Have your camera all set up - ideally on a tripod ..
Take the cover off and the snake will usually be curled up nicely ( especially if you use a bowl ) . They generally stay still for a minute or so for some peculiar reason ...
