aim higher perhaps... your degree probably is of limited use in a generic IT 1st line support role - it is probably a signal that you ought to know enough to handle such a role (though quality of grads can vary so that isn't a given for employers)
if you really want to do 1st line support then perhaps spell out your skill set explicitly - tailor it to the ads you've seen
one thing a friend of mine did about a decade ago when finishing uni without a job lined up was to set up a small computer shop website, wasn't completely fake, he got a couple of actual orders from random people and also built some computers for friend/relatives too... point was he could - without telling a total lie - put down actual work experience
frankly if you've got a degree I'd suggest aiming higher than generic 1st line support roles... though you've not mentioned institution or grade - below a 2:1 and at a institution with a lesser brand name and you could struggle more
