First, don't try to change all those values in one setting.

Which values actually need to be changed? root=/dev/ram0 is the
default for a ramdisk, ip=dhcp is default for base.

Not all TFTP deployments are U-Boot, so you need to let us know if you
are using U-Boot or something else.

You can define console_device to change the value passed to console=
but the baud rate should include parity and databits as well, so
115200n8 - those are defaults.

{% set console_device = "serial1" %}

Generally, do not change any variable prefixed with base_ because the
change will not take effect. There will be an alternative argument for
each use of the base_ variable.

See https://master.lavasoftware.org/static/docs/v2/simple-admin.html#overriding-device-configuration

Simplest thing to do is make changes in the device dictionary and
check the rendered YAML output - there is no need to run a test job
until you are sure that the various settings, combined, have given you
the right values.
