It will take drilling a hole at the same spot that the groove is on a no-holes link.

If done well, the hole drilled can then be machined to be similar to a grooved end link; a single hole could suffice and be left there, or the hole could be weld-filled. The case should not be damaged if done carefully.

In the meantime, the bracelet can be unscrewed at a removable link and re-attached to the other half to be fully functional until the work can be performed.
