Optimizing Netdata Disk Charts: Excluding "Reserved for Root" Sections

I've configured the Netdata Disk Statistics plugin to monitor disk performance metrics on my system. While the charts provide valuable insights into disk usage and performance.

I'd like to exclude / remove reserved for root from the graphs ( /var/lib/docker )

Here's a summary of my current Netdata configuration:

[plugin:proc:diskspace]
    update every = 60
    exclude space metrics on paths = /proc/* /sys/* /var/run/user/* /run/user/* /var/lib/docker/* /dev /dev/shm /run /run/* /opt/scorer/lib/stack-mgr/stacks/custom
    inodes usage for all disks = no

[plugin:proc:/proc/diskstats]
    exclude disks = loop* ram* boot rootfs rex-kmshare ext4
    merged operations for all disks = no
    backlog for all disks = no
    i/o time for all disks = no
    enable new disks detected at runtime = no

[plugin:proc:/proc/diskstats:sda]
    enable = yes
    enable performance metrics = auto
    bandwidth = auto
    operations = auto
    merged operations = no
    queued operations = auto
    utilization percentage = auto
    extended operations = no

[plugin:proc:/proc/diskstats:nvme0n1]
    enable = yes
    enable performance metrics = auto
    bandwidth = auto
    operations = auto
    merged operations = no
    queued operations = auto
    utilization percentage = auto
    extended operations = no

As you can see, I've excluded certain paths from disk space metrics to avoid cluttering the charts. However, I'm unsure how to reserved for root from the graphs ( /var/lib/docker ) & ( /opt/scorer/log )

Here's the output of lsblk -f for reference:

                                                                                   /var/lib/docker

Could someone provide guidance on how to exclude reserved for root from the graphs ( /var/lib/docker ) & ( /opt/scorer/log )
Your help would be greatly appreciated! Thanks in advance.

Expected behavior

reserved for root must be skip/hide from the graphs /var/lib/docker
