Whose idea is it to birth these? It may seem easier, but to get a good end product it's actually more work than a bound quilt, imo. I've never birthed anything bigger than a doll quilt. Try a practice one, perhaps the size of a placemat, and see if the amount of lint is noticeable. If you have a batting that doesn't produce lint and doesn't catch on the feed dogs, perhaps it's doable.
If your machine has a programmed 4-step buttonhole, you can use one end of that to make tack-down stitches at intervals all over the birthed quilt. Start in the center and work out and place them in the ditch so they don't show much on the front. This stitch pattern starts and ends with a few stitches in place to help lock it. If there's no buttonhole stitch pattern, you can use a wide zigzag and 0 length, but it's a little more tedious, or go forward and back with a straight stitch. In fact, tacking/tying would feel like a lot (hours!) of extra work to me in addition to the quilting. The easiest way would be to quilt in the usual way and bring the back to the front to bind. Here's a tutorial that explains a method that will work on any size quilt:
