Not without adding lateral bracing! Once you add siding this structure becomes a sail and a strong wind will crumple it. For the front opening you need substantial lateral bracing (big header, strong moment connector). You can look up a portal frame wall for an engineered detail. You need a bottom plate that is connected to the slab (1/2” wedge anchors), then full framing and sheathing. This is not a small job, but doable. Most cities make you pull a permit for this type of garage conversion.
