/sys/fs/pstore won't work on poco m3 android, is there a way to fix it?

I'm trying to use pstore logs on my Poco M3. I tried everything. PSTORE configs are activated on the kernel, pstore module is loaded on the phone, phone is rooted, /sys/fs/pstore is mounted automatically but never contains anything.

130|citrus:/ # dmesg | grep pstore[    0.094327] console [pstore-1] enabled[    0.094468] pstore: Registered ramoops as persistent store backend[    1.065975] pstore: Using compression: deflate[   98.052156] type=1400 audit(1654268897.690:3752): avc: denied { read } for comm="ls" name="/" dev="pstore" ino=1197 scontext=u:r:shell:s0 tcontext=u:object_r:pstorefs:s0 tclass=dir permissive=1[   98.052450] type=1400 audit(1654268897.690:3753): avc: denied { open } for comm="ls" path="/sys/fs/pstore" dev="pstore" ino=1197 scontext=u:r:shell:s0 tcontext=u:object_r:pstorefs:s0 tclass=dir permissive=1

it looks like selinux is blocking ls on /sys/fs/pstore. Is there a way to make it always allow ls on /sys/fs/pstore, even after reboot?

I already added androidboot.selinux=permissive to my boot command line and it's recognized on the phone:

130|citrus:/ # getenforcePermissive 

UPDATE: I just learned that permissive means just logging without blocking, so this is not blocking, my pstore is indeed empty. Am I right?
