I'm assuming you mean the 9th of February as it seems that the ISS will also be close to transiting the moon from here at about 22:44 pm. Having captured a couple of transits in the past I would recommend a focal length of at least 600mm and with a full frame 6D, 800 to 1000mm would give you better image scale. Do you have a tracking mount or just a camera tripod, if only a tripod, good luck.
Depending on the distance of the ISS from your location at the time of the transit, it will somewhere between 0.6 sec duration and 60 arc sec. in angular size if close and 1.3 sec duration and 25 arc sec. if further away. Just checked the full details of the transit using and get 9/02/20 22:54':19.46" Angular size 30.44 " and duration of 1.19 sec.
To give you some idea of the image scale here is an image of the Moon and Saturn taken with a 550D and ED80 ( 600mm F/L ) Saturn is approx. the same angular size as the ISS for your transit.
