Is the alternative double-sided two way ranging implementation somewhere available?

I have purchased an MDEK1001 kit and I am interested in implementing the Alt-DS-TWR (An alternative double-sided two-way ranging method | IEEE Conference Publication | IEEE Xplore) method for doing mesh ranging (all towards all) between the modules. Is this method somewhere available implemented? Does it make sense to use that instead of the simple DS-TWR? Is this even possible with the MDEK?
