No, not if you have only lost pressurisation capability, it depends on the situation. It could be that a bleed valve or both packs or an outflow valve have gone unserviceable, but you can fly safely without those, as long as the plane is otherwise healthy.
So there is no automatic need to divert - it's not going to fall out of the sky or explode. This assumes reasonable weather and flying conditions at FL100, and sufficient fuel of course.
Making that call is what the pilots will decide as part of their TDODAR deliberations, along with passenger and crew comfort.
