Increase the open file limit on OBS?

I maintain the vscode package. In the latest version, all systems and architectures on OBS started failing with `EMFILE: too many open files, open '/home/abuild/rpmbuild/BUILD/[blah]'` (i assume this is being thrown by a nodejs process). The package builds fine in a chroot on my Tumbleweed computer where `ulimit -aH` shows the limit for open files as 524288. Is it possible to reconfigure the OBS kernel to allow this many too?
