Doubtful.

We could get started, probably make some habitable enclosures, but before we can alter the global atmosphere--a fundamental prerequisite of any other global-scale terraforming we might attempt--there are significant impediments to overcome that are as-yet beyond our capacity.

Namely, the lack of an Ozone layer and a global magnetic field. Both of these serve on our world to protect the atmosphere and the surface from radiation and solar wind. Without them, any gas we pump into the air around Mars is just going to bleed off into space like its first atmosphere did.

Solar powered electromagnets the size of Rhode island at both poles. The ozone comes after.

Significantly smaller space based devices would do the job.

We could deploy a big electromagnetic dipole at the Sun-Mars L1 point.

This would solve the solar wind problem and even reverse the atmosphere loss on its own.

NASA has already done a study on this and it looks promising (ie. Could work)
