time machine backup on NAS using WebDav?

Hi, I regularly use Time Machine to backup my mac on a NAS using my home network (Synology instructions are for configuration using the afp protocol). I have been travelling a lot lately and Time Machine backups on my NAS are not a choice. I’m using an external drive as a temporary strategy until back home. Anybody knows if it is possible to configure Time machine to backup on a NAS using WebDav protocol? If so, how to do it?

I appreciate any information / help with this.
