I try, but it is difficult. For compiling own modules I need kernel-default-devel, kernel-devel, kernel-syms and kernel-source. With stable-backports kernel-default, default-devel and syms are only lp152 and not lp153. I just tried it with the newest version some minutes ago. This afternoon I tried kernel head. And there I needed kernel-syms and kernel-default-devel for lp153, but yast only found the version lp152 and therefore wanted to install parts of kernel 5.3.x. I can't get rid of kernel 5.3.x. I hope, I'm clear. Sorry.
