Not with MIAB, no. This would be entirely unsupported. Maybe possible using NFS exports from a central storage server mounted where MIAB expects itself to be, but you could run into untold trouble with that.
Although this is a really old post, I’ve a lot of experience with this kind of setup. In my current situation, my mail volume is that low, that MIAB is even overkill, but if you need support in this.
