HDRP Lit Shader: How to disable Transparency "Blend preserve" through script?

Hello, i've been trying to disable through a script the "Blend preserve" property of the Transparency Blend Mode of the HDRP Lit Shader. The script does uncheck the "Blend preserve" box in the Inspector, but the material doesn't update unless i click the box manually. Am i missing something in the script?

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class ToggleFadeSettings : MonoBehaviour
 {
     Material m;
 
     // Start is called before the first frame update
     void Start()
     {
         m = GetComponent<Renderer>().material;
     }
 
     // Update is called once per frame
     void Update()
     {
         if (Input.GetKeyDown(KeyCode.Space)) {
         m.EnableKeyword(" _BLENDMODE_PRESERVE_SPECULAR_LIGHTING");
         m.SetFloat("_EnableBlendModePreserveSpecularLighting", 0f);
         }
 
     }
 }

Bump and further details:

In order to see which keywords are enabled, i updated the Update function to this:

     void Update()
     {
         if (Input.Get$$anonymous$$eyDown($$anonymous$$eyCode.Space)) {
             m.Enable$$anonymous$$eyword("_BLEND$$anonymous$$ODE_PRESERVE_SPECULAR_LIGHTING");
             m.SetFloat("_EnableBlend$$anonymous$$odePreserveSpecularLighting", 0f);
             
             foreach(string k in m.shader$$anonymous$$eywords) {
                 Debug.Log(k);
             }
         }
 
     }

This is what i get: alt text
