Problem applying time-varying SST in idealized WRF SCM

Hello, I am trying to run a modified version of the WRF SCM model. I'm trying to apply a diurnal cycle of just SSTs over the entire spatial domain. However, the SSTs aren't being applied. Instead, the SST used is being pulled from the input_soil file, and is time invariant. I've taken over the existing model infrastructure from some previous experiments and I'm not very knowledgeable about WRF at all, but as far as I understand I should have the inputs set up correctly, so I don't understand why it's not reading the SST inputs from the forcing file that I made. I must have some options incorrectly specified, or my forcing files incorrectly made, but I don't know what exactly is wrong, and I thought someone more experience might be able to tell what is wrong much faster. I've attached my namelist.input file, and can also provide the SST input forcing if that would be helpful, but it's just a .nc file made with xarray consisting of a sinusoidal temperature series with dimensions Time, west_east, and south_north.

If anyone could help me, I would greatly appreciate it.
Thanks you in advance.

SST_update only works for real-data case. Due to limited human power, unfortunately we cannot support codes modified by individual users.

Thank you for your response. Is there any way of applying a changing SST in the default configurations of idealized WRF simulations? I understand that you cannot support modified codes, but this is an aspect of the model which I'm quite sure has not been modified.
 
For real-data case, time-varying SST is derived from forcing data, saved as a datafile in netCDF format and read into WRF at specified time during the model run. All the ideal cases in the official release of WRF don't implement specified lateral boundaries and thus doesn't include capability to read data at specified intervals. Based on this consideration, I am thinking that probably you can hardcod time-varying SST in the ideal case. I suppose this is way easier than following the approach of sst_update for real-data case.
