mitigations=off is all you need. The setting turns off all mitigations that can be turned off. Repeating a long and, by the way, very obsolete list of individual vulnerability mitigation options is entirely unnecessary.

The kernel parameters are documented in kernel sources /Documentation/admin-guide/kernel-parameters.txt, and also included as plain text in the kernel documentation page: https://www.kernel.org/doc/html/v6.2/admin-guide/kernel-parameters.html. Search for mitigation=, and read the list of mitigations that are turned off by this option. Replace v6.2 with your kernel version; https://www.kernel.org/doc/html/ lists all available versions. The part /admin-guide/kernel-parameters.html never changes.
