You’re using refind, you need to specify the quiet splash parameters in refind config. You can do this every time you boot by manually editing the entry, for example if you want to test that editing this would work, or you can edit the config file with the boot parameters.
I don’t know how you have your refind configured, mine has a /boot/refind_linux.conf file where I can put the boot parameters, e.g. mine looks like this:
<span style="color:#323232;">"Boot with standard options" "rw root=/dev/nvme1n1p2"
</span><span style="color:#323232;">"Boot to single-user mode" "rw root=/dev/nvme1n1p2 single"
</span><span style="color:#323232;">"Boot with minimal options" "ro root=/dev/nvme1n1p2"
</span>
