Bootup/Startup Script Not Working for nVidia GPU Clock Offset - centos

Question

Trying to change GPU Graphics and Memory Transfer Rate Clock Offset on my nVidia EVGA 1030 SC on bootup. I am a linux noob here using Rocky Linux 9.
Question:
How do I check my current set values for GPUGraphicsClockOffsetAllPerformanceLevels and GPUMemoryTransferRateOffsetAllPerformanceLevels?
Currently I am checking by starting up nVidia X Server then look for the values in Graphics Clock Offset and Memory Transfer Rate Offset under the PowerMizer tab. Is there a better way? I don't even really know if that is always up to date...
What did I do wrong and what do I need to change to fix my bootup script below to work?
I think my bootup script is NOT working because the PowerMizer in nVidia X Server does NOT show clock offset values of 50MHz and 200MHz for Graphics and Memory Transfer Rates, respectively, when I boot with my script. It only shows 0 and 0.
However, it does show 50MHz and 200MHz when I enter the following 3 commands line after line directly in bash terminal.
nvidia-smi -pm 1
nvidia-settings -a [gpu:0]/"GPUGraphicsClockOffsetAllPerformanceLevels=50"
nvidia-settings -a [gpu:0]/"GPUMemoryTransferRateOffsetAllPerformanceLevels=200"
Below is the bootup script...
i.
Wrote a shell script file named nVidiaStartUp.sh and placed it in: /etc/rc.d/init.d
nVidiaStartUp.sh contains
#!/bin/bash
nvidia-smi -pm 1
nvidia-settings -a [gpu:0]/"GPUGraphicsClockOffsetAllPerformanceLevels=50"
nvidia-settings -a [gpu:0]/"GPUMemoryTransferRateOffsetAllPerformanceLevels=200"
ii.
In Terminal, executed chmod +x /etc/rc.d/init.d/nVidiaStartUp.sh
iii.
Added a script named nVidiaStartUp.service in /etc/systemd/system with contents below
[Unit]
Description=nVidia Startup Script Call with Undervolt
After=getty.target
[Service]
Type=simple
ExecStart=/etc/rc.d/init.d/nVidiaStartUp.sh
TimeoutStartSec=0
#RemainAfterExit=yes
[Install]
WantedBy=default.target
#WantedBy=graphical.target
#WantedBy=multi-user.target
iv.
Ran in terminal
systemctl enable nVidiaStartUp.service
v.
Reboot and then I check my clockoffset under PowerMizer in nVidia X Server. I don't see 50MHz and 200MHz. I only see 0 and 0. That seems to imply my bootup script isn't working? Please help!

Additional background info:
I have installed nVidia driver and it loads with proper GPU information. Here is what it shows after running nvidia-smi
